+This is the contents of some of the drivers/usb/serial/ files that had  old
+changelog comments.  They were quite old, and out of date, and we don't keep
+them anymore, so I've put them here, away from the source files, in case
+people still care to see them.

+-----------------------------------------------------------------------
+usb-serial.h Change Log comments:
+
+ (03/26/2002) gkh
+	removed the port->tty check from port_paranoia_check() due to serial
+	consoles not having a tty device assigned to them.
+
+ (12/03/2001) gkh
+	removed active from the port structure.
+	added documentation to the usb_serial_device_type structure
+
+ (10/10/2001) gkh
+	added vendor and product to serial structure.  Needed to determine device
+	owner when the device is disconnected.
+
+ (05/30/2001) gkh
+	added sem to port structure and removed port_lock
+
+ (10/05/2000) gkh
+	Added interrupt_in_endpointAddress and bulk_in_endpointAddress to help
+	fix bug with urb->dev not being set properly, now that the usb core
+	needs it.
+
+ (09/11/2000) gkh
+	Added usb_serial_debug_data function to help get rid of #DEBUG in the
+	drivers.
+
+ (08/28/2000) gkh
+	Added port_lock to port structure.
+
+ (08/08/2000) gkh
+	Added open_count to port structure.
+
+ (07/23/2000) gkh
+	Added bulk_out_endpointAddress to port structure.
+
+ (07/19/2000) gkh, pberger, and borchers
+	Modifications to allow usb-serial drivers to be modules.
+
+-----------------------------------------------------------------------
+usb-serial.c Change Log comments:
+
+ (12/10/2002) gkh
+	Split the ports off into their own struct device, and added a
+	usb-serial bus driver.
+
+ (11/19/2002) gkh
+	removed a few #ifdefs for the generic code and cleaned up the failure
+	logic in initialization.
+
+ (10/02/2002) gkh
+	moved the console code to console.c and out of this file.
+
+ (06/05/2002) gkh
+	moved location of startup() call in serial_probe() until after all
+	of the port information and endpoints are initialized.  This makes
+	things easier for some drivers.
+
+ (04/10/2002) gkh
+	added serial_read_proc function which creates a
+	/proc/tty/driver/usb-serial file.
+
+ (03/27/2002) gkh
+	Got USB serial console code working properly and merged into the main
+	version of the tree.  Thanks to Randy Dunlap for the initial version
+	of this code, and for pushing me to finish it up.
+	The USB serial console works with any usb serial driver device.
+
+ (03/21/2002) gkh
+	Moved all manipulation of port->open_count into the core.  Now the
+	individual driver's open and close functions are called only when the
+	first open() and last close() is called.  Making the drivers a bit
+	smaller and simpler.
+	Fixed a bug if a driver didn't have the owner field set.
+
+ (02/26/2002) gkh
+	Moved all locking into the main serial_* functions, instead of having
+	the individual drivers have to grab the port semaphore.  This should
+	reduce races.
+	Reworked the MOD_INC logic a bit to always increment and decrement, even
+	if the generic driver is being used.
+
+ (10/10/2001) gkh
+	usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
+	help prevent child drivers from accessing the device since it is now
+	gone.
+
+ (09/13/2001) gkh
+	Moved generic driver initialize after we have registered with the USB
+	core.  Thanks to Randy Dunlap for pointing this problem out.
+
+ (07/03/2001) gkh
+	Fixed module paramater size.  Thanks to John Brockmeyer for the pointer.
+	Fixed vendor and product getting defined through the MODULE_PARM macro
+	if the Generic driver wasn't compiled in.
+	Fixed problem with generic_shutdown() not being called for drivers that
+	don't have a shutdown() function.
+
+ (06/06/2001) gkh
+	added evil hack that is needed for the prolific pl2303 device due to the
+	crazy way its endpoints are set up.
+
+ (05/30/2001) gkh
+	switched from using spinlock to a semaphore, which fixes lots of problems.
+
+ (04/08/2001) gb
+	Identify version on module load.
+
+ 2001_02_05 gkh
+	Fixed buffer overflows bug with the generic serial driver.  Thanks to
+	Todd Squires <squirest@xxxxxxx> for fixing this.
+
+ (01/10/2001) gkh
+	Fixed bug where the generic serial adaptor grabbed _any_ device that was
+	offered to it.
+
+ (12/12/2000) gkh
+	Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
+	moved them to the serial_open and serial_close functions.
+	Also fixed bug with there not being a MOD_DEC for the generic driver
+	(thanks to Gary Brubaker for finding this.)
+
+ (11/29/2000) gkh
+	Small NULL pointer initialization cleanup which saves a bit of disk image
+
+ (11/01/2000) Adam J. Richter
+	instead of using idVendor/idProduct pairs, usb serial drivers
+	now identify their hardware interest with usb_device_id tables,
+	which they usually have anyhow for use with MODULE_DEVICE_TABLE.
+
+ (10/05/2000) gkh
+	Fixed bug with urb->dev not being set properly, now that the usb
+	core needs it.
+
+ (09/11/2000) gkh
+	Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (08/28/2000) gkh
+	Added port_lock to port structure.
+	Added locks for SMP safeness to generic driver
+	Fixed the ability to open a generic device's port more than once.
+
+ (07/23/2000) gkh
+	Added bulk_out_endpointAddress to port structure.
+
+ (07/19/2000) gkh, pberger, and borchers
+	Modifications to allow usb-serial drivers to be modules.
+
+ (07/03/2000) gkh
+	Added more debugging to serial_ioctl call
+
+ (06/25/2000) gkh
+	Changed generic_write_bulk_callback to not call wake_up_interruptible
+	directly, but to have port_softint do it at a safer time.
+
+ (06/23/2000) gkh
+	Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (05/22/2000) gkh
+	Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
+	removed from the individual device source files.
+
+ (05/03/2000) gkh
+	Added the Digi Acceleport driver from Al Borchers and Peter Berger.
+
+ (05/02/2000) gkh
+	Changed devfs and tty register code to work properly now. This was based on
+	the ACM driver changes by Vojtech Pavlik.
+
+ (04/27/2000) Ryan VanderBijl
+ 	Put calls to *_paranoia_checks into one function.
+
+ (04/23/2000) gkh
+	Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
+	Moved when the startup code printed out the devices that are supported.
+
+ (04/19/2000) gkh
+	Added driver for ZyXEL omni.net lcd plus ISDN TA
+	Made startup info message specify which drivers were compiled in.
+
+ (04/03/2000) gkh
+	Changed the probe process to remove the module unload races.
+	Changed where the tty layer gets initialized to have devfs work nicer.
+	Added initial devfs support.
+
+ (03/26/2000) gkh
+	Split driver up into device specific pieces.
+
+ (03/19/2000) gkh
+	Fixed oops that could happen when device was removed while a program
+	was talking to the device.
+	Removed the static urbs and now all urbs are created and destroyed
+	dynamically.
+	Reworked the internal interface. Now everything is based on the
+	usb_serial_port structure instead of the larger usb_serial structure.
+	This fixes the bug that a multiport device could not have more than
+	one port open at one time.
+
+ (03/17/2000) gkh
+	Added config option for debugging messages.
+	Added patch for keyspan pda from Brian Warner.
+
+ (03/06/2000) gkh
+	Added the keyspan pda code from Brian Warner <warner@xxxxxxxxxx>
+	Moved a bunch of the port specific stuff into its own structure. This
+	is in anticipation of the true multiport devices (there's a bug if you
+	try to access more than one port of any multiport device right now)
+
+ (02/21/2000) gkh
+	Made it so that any serial devices only have to specify which functions
+	they want to overload from the generic function calls (great,
+	inheritance in C, in a driver, just what I wanted...)
+	Added support for set_termios and ioctl function calls. No drivers take
+	advantage of this yet.
+	Removed the #ifdef MODULE, now there is no module specific code.
+	Cleaned up a few comments in usb-serial.h that were wrong (thanks again
+	to Miles Lott).
+	Small fix to get_free_serial.
+
+ (02/14/2000) gkh
+	Removed the Belkin and Peracom functionality from the driver due to
+	the lack of support from the vendor, and me not wanting people to
+	accidenatly buy the device, expecting it to work with Linux.
+	Added read_bulk_callback and write_bulk_callback to the type structure
+	for the needs of the FTDI and WhiteHEAT driver.
+	Changed all reverences to FTDI to FTDI_SIO at the request of Bill
+	Ryder.
+	Changed the output urb size back to the max endpoint size to make
+	the ftdi_sio driver have it easier, and due to the fact that it didn't
+	really increase the speed any.
+
+ (02/11/2000) gkh
+	Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
+	patch from Miles Lott (milos@xxxxxxxxxx).
+	Fixed bug with not restoring the minor range that a device grabs, if
+	the startup function fails (thanks Miles for finding this).
+
+ (02/05/2000) gkh
+	Added initial framework for the Keyspan PDA serial converter so that
+	Brian Warner has a place to put his code.
+	Made the ezusb specific functions generic enough that different
+	devices can use them (whiteheat and keyspan_pda both need them).
+	Split out a whole bunch of structure and other stuff to a separate
+	usb-serial.h file.
+	Made the Visor connection messages a little more understandable, now
+	that Miles Lott (milos@xxxxxxxxxx) has gotten the Generic channel to
+	work. Also made them always show up in the log file.
+
+ (01/25/2000) gkh
+	Added initial framework for FTDI serial converter so that Bill Ryder
+	has a place to put his code.
+	Added the vendor specific info from Handspring. Now we can print out
+	informational debug messages as well as understand what is happening.
+
+ (01/23/2000) gkh
+	Fixed problem of crash when trying to open a port that didn't have a
+	device assigned to it. Made the minor node finding a little smarter,
+	now it looks to find a continuous space for the new device.
+
+ (01/21/2000) gkh
+	Fixed bug in visor_startup with patch from Miles Lott (milos@xxxxxxxxxx)
+	Fixed get_serial_by_minor which was all messed up for multi port
+	devices. Fixed multi port problem for generic devices. Now the number
+	of ports is determined by the number of bulk out endpoints for the
+	generic device.
+
+ (01/19/2000) gkh
+	Removed lots of cruft that was around from the old (pre urb) driver
+	interface.
+	Made the serial_table dynamic. This should save lots of memory when
+	the number of minor nodes goes up to 256.
+	Added initial support for devices that have more than one port.
+	Added more debugging comments for the Visor, and added a needed
+	set_configuration call.
+
+ (01/17/2000) gkh
+	Fixed the WhiteHEAT firmware (my processing tool had a bug)
+	and added new debug loader firmware for it.
+	Removed the put_char function as it isn't really needed.
+	Added visor startup commands as found by the Win98 dump.
+
+ (01/13/2000) gkh
+	Fixed the vendor id for the generic driver to the one I meant it to be.
+
+ (01/12/2000) gkh
+	Forget the version numbering...that's pretty useless...
+	Made the driver able to be compiled so that the user can select which
+	converter they want to use. This allows people who only want the Visor
+	support to not pay the memory size price of the WhiteHEAT.
+	Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
+	grabbed the root hub. Not good.
+
+ version 0.4.0 (01/10/2000) gkh
+	Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
+	device. Added startup function to allow firmware to be downloaded to
+	a device if it needs to be.
+	Added firmware download logic to the WhiteHEAT device.
+	Started to add #defines to split up the different drivers for potential
+	configuration option.
+
+ version 0.3.1 (12/30/99) gkh
+      Fixed problems with urb for bulk out.
+      Added initial support for multiple sets of endpoints. This enables
+      the Handspring Visor to be attached successfully. Only the first
+      bulk in / bulk out endpoint pair is being used right now.
+
+ version 0.3.0 (12/27/99) gkh
+	Added initial support for the Handspring Visor based on a patch from
+	Miles Lott (milos@xxxxxxxxxxxxxxxxx)
+	Cleaned up the code a bunch and converted over to using urbs only.
+
+ version 0.2.3 (12/21/99) gkh
+	Added initial support for the Connect Tech WhiteHEAT converter.
+	Incremented the number of ports in expectation of getting the
+	WhiteHEAT to work properly (4 ports per connection).
+	Added notification on insertion and removal of what port the
+	device is/was connected to (and what kind of device it was).
+
+ version 0.2.2 (12/16/99) gkh
+	Changed major number to the new allocated number. We're legal now!
+
+ version 0.2.1 (12/14/99) gkh
+	Fixed bug that happens when device node is opened when there isn't a
+	device attached to it. Thanks to marek@xxxxxxxxxxxx for noticing this.
+
+ version 0.2.0 (11/10/99) gkh
+	Split up internals to make it easier to add different types of serial
+	converters to the code.
+	Added a "generic" driver that gets it's vendor and product id
+	from when the module is loaded. Thanks to David E. Nelson (dnelson@xxxxxxxx)
+	for the idea and sample code (from the usb scanner driver.)
+	Cleared up any licensing questions by releasing it under the GNU GPL.
+
+ version 0.1.2 (10/25/99) gkh
+ 	Fixed bug in detecting device.
+
+ version 0.1.1 (10/05/99) gkh
+ 	Changed the major number to not conflict with anything else.
+
+ version 0.1 (09/28/99) gkh
+ 	Can recognize the two different devices and start up a read from
+	device when asked to. Writes also work. No control signals yet, this
+	all is vendor specific data (i.e. no spec), also no control for
+	different baud rates or other bit settings.
+	Currently we are using the same devid as the acm driver. This needs
+	to change.

+visor.c Change Log comments:
+
+ (06/03/2003) Judd Montgomery <judd at jpilot.org>
+     Added support for module parameter options for untested/unknown
+     devices.
+
+ (03/09/2003) gkh
+	Added support for the Sony Clie NZ90V device.  Thanks to Martin Brachtl
+	<brachtl@xxxxxxxxxx> for the information.
+
+ (03/05/2003) gkh
+	Think Treo support is now working.
+
+ (04/03/2002) gkh
+	Added support for the Sony OS 4.1 devices.  Thanks to Hiroyuki ARAKI
+	<hiro@xxxxxxxxx> for the information.
+
+ (03/27/2002) gkh
+	Removed assumptions that port->tty was always valid (is not true
+	for usb serial console devices.)
+
+ (03/23/2002) gkh
+	Added support for the Palm i705 device, thanks to Thomas Riemer
+	<tom@xxxxxxxxxxx> for the information.
+
+ (03/21/2002) gkh
+	Added support for the Palm m130 device, thanks to Udo Eisenbarth
+	<udo.eisenbarth@xxxxxx> for the information.
+
+ (02/27/2002) gkh
+	Reworked the urb handling logic.  We have no more pool, but dynamically
+	allocate the urb and the transfer buffer on the fly.  In testing this
+	does not incure any measurable overhead.  This also relies on the fact
+	that we have proper reference counting logic for urbs.
+
+ (02/21/2002) SilaS
+  Added initial support for the Palm m515 devices.
+
+ (02/14/2002) gkh
+	Added support for the Clie S-360 device.
+
+ (12/18/2001) gkh
+	Added better Clie support for 3.5 devices.  Thanks to Geoffrey Levand
+	for the patch.
+
+ (11/11/2001) gkh
+	Added support for the m125 devices, and added check to prevent oopses
+	for Clié devices that lie about the number of ports they have.
+
+ (08/30/2001) gkh
+	Added support for the Clie devices, both the 3.5 and 4.0 os versions.
+	Many thanks to Daniel Burke, and Bryan Payne for helping with this.
+
+ (08/23/2001) gkh
+	fixed a few potential bugs pointed out by Oliver Neukum.
+
+ (05/30/2001) gkh
+	switched from using spinlock to a semaphore, which fixes lots of problems.
+
+ (05/28/2000) gkh
+	Added initial support for the Palm m500 and Palm m505 devices.
+
+ (04/08/2001) gb
+	Identify version on module load.
+
+ (01/21/2000) gkh
+	Added write_room and chars_in_buffer, as they were previously using the
+	generic driver versions which is all wrong now that we are using an urb
+	pool.  Thanks to Wolfgang Grandegger for pointing this out to me.
+	Removed count assignment in the write function, which was not needed anymore
+	either.  Thanks to Al Borchers for pointing this out.
+
+ (12/12/2000) gkh
+	Moved MOD_DEC to end of visor_close to be nicer, as the final write
+	message can sleep.
+
+ (11/12/2000) gkh
+	Fixed bug with data being dropped on the floor by forcing tty->low_latency
+	to be on.  Hopefully this fixes the OHCI issue!
+
+ (11/01/2000) Adam J. Richter
+	usb_device_id table support
+
+ (10/05/2000) gkh
+	Fixed bug with urb->dev not being set properly, now that the usb
+	core needs it.
+
+ (09/11/2000) gkh
+	Got rid of always calling kmalloc for every urb we wrote out to the
+	device.
+	Added visor_read_callback so we can keep track of bytes in and out for
+	those people who like to know the speed of their device.
+	Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (09/06/2000) gkh
+	Fixed oops in visor_exit.  Need to uncomment usb_unlink_urb call _after_
+	the host controller drivers set urb->dev = NULL when the urb is finished.
+
+ (08/28/2000) gkh
+	Added locks for SMP safeness.
+
+ (08/08/2000) gkh
+	Fixed endian problem in visor_startup.
+	Fixed MOD_INC and MOD_DEC logic and the ability to open a port more
+	than once.
+
+ (07/23/2000) gkh
+	Added pool of write urbs to speed up transfers to the visor.
+
+ (07/19/2000) gkh
+	Added module_init and module_exit functions to handle the fact that this
+	driver is a loadable module now.
+
+ (07/03/2000) gkh
+	Added visor_set_ioctl and visor_set_termios functions (they don't do much
+	of anything, but are good for debugging.)
+
+ (06/25/2000) gkh
+	Fixed bug in visor_unthrottle that should help with the disconnect in PPP
+	bug that people have been reporting.
+
+ (06/23/2000) gkh
+	Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (04/27/2000) Ryan VanderBijl
+ 	Fixed memory leak in visor_close
+
+ (03/26/2000) gkh
+	Split driver up into device specific pieces.
+
+-----------------------------------------------------------------------
+pl2303.c Change Log comments:
+
+ 2002_Mar_26 gkh
+	allowed driver to work properly if there is no tty assigned to a port
+	(this happens for serial console devices.)
+
+ 2001_Oct_06 gkh
+	Added RTS and DTR line control.  Thanks to joe@xxxxxxxx for parts of it.
+
+ 2001_Sep_19 gkh
+	Added break support.
+
+ 2001_Aug_30 gkh
+	fixed oops in write_bulk_callback.
+
+ 2001_Aug_28 gkh
+	reworked buffer logic to be like other usb-serial drivers.  Hopefully
+	removing some reported problems.
+
+ 2001_Jun_06 gkh
+	finished porting to 2.4 format.

------------------------------------------------------------------------
-usb-serial.h Change Log comments:

-usb-serial.c Change Log comments:
-
- (12/10/2002) gkh
-	Split the ports off into their own struct device, and added a
-	usb-serial bus driver.
-
- (11/19/2002) gkh
-	removed a few #ifdefs for the generic code and cleaned up the failure
-	logic in initialization.
-
- (10/02/2002) gkh
-	moved the console code to console.c and out of this file.
-
- (06/05/2002) gkh
-	moved location of startup() call in serial_probe() until after all
-	of the port information and endpoints are initialized.  This makes
-	things easier for some drivers.
-
- (04/10/2002) gkh
-	added serial_read_proc function which creates a
-	/proc/tty/driver/usb-serial file.
-
- (03/27/2002) gkh
-	Got USB serial console code working properly and merged into the main
-	version of the tree.  Thanks to Randy Dunlap for the initial version
-	of this code, and for pushing me to finish it up.
-	The USB serial console works with any usb serial driver device.
-
- (03/21/2002) gkh
-	Moved all manipulation of port->open_count into the core.  Now the
-	individual driver's open and close functions are called only when the
-	first open() and last close() is called.  Making the drivers a bit
-	smaller and simpler.
-	Fixed a bug if a driver didn't have the owner field set.
-
- (02/26/2002) gkh
-	Moved all locking into the main serial_* functions, instead of having
-	the individual drivers have to grab the port semaphore.  This should
-	reduce races.
-	Reworked the MOD_INC logic a bit to always increment and decrement, even
-	if the generic driver is being used.
-
- (10/10/2001) gkh
-	usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
-	help prevent child drivers from accessing the device since it is now
-	gone.
-
- (09/13/2001) gkh
-	Moved generic driver initialize after we have registered with the USB
-	core.  Thanks to Randy Dunlap for pointing this problem out.
-
- (07/03/2001) gkh
-	Fixed module paramater size.  Thanks to John Brockmeyer for the pointer.
-	Fixed vendor and product getting defined through the MODULE_PARM macro
-	if the Generic driver wasn't compiled in.
-	Fixed problem with generic_shutdown() not being called for drivers that
-	don't have a shutdown() function.
-
- (06/06/2001) gkh
-	added evil hack that is needed for the prolific pl2303 device due to the
-	crazy way its endpoints are set up.
-
- (05/30/2001) gkh
-	switched from using spinlock to a semaphore, which fixes lots of problems.
-
- (04/08/2001) gb
-	Identify version on module load.
-
- 2001_02_05 gkh
-	Fixed buffer overflows bug with the generic serial driver.  Thanks to
-	Todd Squires <squirest@xxxxxxx> for fixing this.
-
- (01/10/2001) gkh
-	Fixed bug where the generic serial adaptor grabbed _any_ device that was
-	offered to it.
-
- (12/12/2000) gkh
-	Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
-	moved them to the serial_open and serial_close functions.
-	Also fixed bug with there not being a MOD_DEC for the generic driver
-	(thanks to Gary Brubaker for finding this.)
-
- (11/29/2000) gkh
-	Small NULL pointer initialization cleanup which saves a bit of disk image
-
- (11/01/2000) Adam J. Richter
-	instead of using idVendor/idProduct pairs, usb serial drivers
-	now identify their hardware interest with usb_device_id tables,
-	which they usually have anyhow for use with MODULE_DEVICE_TABLE.
-
- (10/05/2000) gkh
-	Fixed bug with urb->dev not being set properly, now that the usb
-	core needs it.
-
- (09/11/2000) gkh
-	Removed DEBUG #ifdefs with call to usb_serial_debug_data
-
- (08/28/2000) gkh

-	Added bulk_out_endpointAddress to port structure.
-
- (07/19/2000) gkh, pberger, and borchers
-	Modifications to allow usb-serial drivers to be modules.
-
- (07/03/2000) gkh
-	Added more debugging to serial_ioctl call
-
- (06/25/2000) gkh
-	Changed generic_write_bulk_callback to not call wake_up_interruptible
-	directly, but to have port_softint do it at a safer time.
-
- (06/23/2000) gkh
-	Cleaned up debugging statements in a quest to find UHCI timeout bug.
-
- (05/22/2000) gkh
-	Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
-	removed from the individual device source files.
-
- (05/03/2000) gkh
-	Added the Digi Acceleport driver from Al Borchers and Peter Berger.
-
- (05/02/2000) gkh
-	Changed devfs and tty register code to work properly now. This was based on
-	the ACM driver changes by Vojtech Pavlik.
-
- (04/27/2000) Ryan VanderBijl
- 	Put calls to *_paranoia_checks into one function.
-
- (04/23/2000) gkh
-	Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
-	Moved when the startup code printed out the devices that are supported.
-
- (04/19/2000) gkh
-	Added driver for ZyXEL omni.net lcd plus ISDN TA
-	Made startup info message specify which drivers were compiled in.
-
- (04/03/2000) gkh
-	Changed the probe process to remove the module unload races.
-	Changed where the tty layer gets initialized to have devfs work nicer.
-	Added initial devfs support.
-
- (03/26/2000) gkh
-	Split driver up into device specific pieces.
-
- (03/19/2000) gkh
-	Fixed oops that could happen when device was removed while a program
-	was talking to the device.
-	Removed the static urbs and now all urbs are created and destroyed
-	dynamically.
-	Reworked the internal interface. Now everything is based on the
-	usb_serial_port structure instead of the larger usb_serial structure.
-	This fixes the bug that a multiport device could not have more than
-	one port open at one time.
-
- (03/17/2000) gkh
-	Added config option for debugging messages.
-	Added patch for keyspan pda from Brian Warner.
-
- (03/06/2000) gkh
-	Added the keyspan pda code from Brian Warner <warner@xxxxxxxxxx>
-	Moved a bunch of the port specific stuff into its own structure. This
-	is in anticipation of the true multiport devices (there's a bug if you
-	try to access more than one port of any multiport device right now)
-
- (02/21/2000) gkh
-	Made it so that any serial devices only have to specify which functions
-	they want to overload from the generic function calls (great,
-	inheritance in C, in a driver, just what I wanted...)
-	Added support for set_termios and ioctl function calls. No drivers take
-	advantage of this yet.
-	Removed the #ifdef MODULE, now there is no module specific code.
-	Cleaned up a few comments in usb-serial.h that were wrong (thanks again
-	to Miles Lott).
-	Small fix to get_free_serial.
-
- (02/14/2000) gkh
-	Removed the Belkin and Peracom functionality from the driver due to
-	the lack of support from the vendor, and me not wanting people to
-	accidenatly buy the device, expecting it to work with Linux.
-	Added read_bulk_callback and write_bulk_callback to the type structure
-	for the needs of the FTDI and WhiteHEAT driver.
-	Changed all reverences to FTDI to FTDI_SIO at the request of Bill
-	Ryder.
-	Changed the output urb size back to the max endpoint size to make
-	the ftdi_sio driver have it easier, and due to the fact that it didn't
-	really increase the speed any.
-
- (02/11/2000) gkh
-	Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
-	patch from Miles Lott (milos@xxxxxxxxxx).
-	Fixed bug with not restoring the minor range that a device grabs, if
-	the startup function fails (thanks Miles for finding this).
-
- (02/05/2000) gkh
-	Added initial framework for the Keyspan PDA serial converter so that
-	Brian Warner has a place to put his code.
-	Made the ezusb specific functions generic enough that different
-	devices can use them (whiteheat and keyspan_pda both need them).
-	Split out a whole bunch of structure and other stuff to a separate
-	usb-serial.h file.
-	Made the Visor connection messages a little more understandable, now
-	that Miles Lott (milos@xxxxxxxxxx) has gotten the Generic channel to
-	work. Also made them always show up in the log file.
-
- (01/25/2000) gkh
-	Added initial framework for FTDI serial converter so that Bill Ryder
-	has a place to put his code.
-	Added the vendor specific info from Handspring. Now we can print out
-	informational debug messages as well as understand what is happening.
-
- (01/23/2000) gkh
-	Fixed problem of crash when trying to open a port that didn't have a
-	device assigned to it. Made the minor node finding a little smarter,
-	now it looks to find a continuous space for the new device.
-
- (01/21/2000) gkh
-	Fixed bug in visor_startup with patch from Miles Lott (milos@xxxxxxxxxx)
-	Fixed get_serial_by_minor which was all messed up for multi port
-	devices. Fixed multi port problem for generic devices. Now the number
-	of ports is determined by the number of bulk out endpoints for the
-	generic device.
-
- (01/19/2000) gkh
-	Removed lots of cruft that was around from the old (pre urb) driver
-	interface.
-	Made the serial_table dynamic. This should save lots of memory when
-	the number of minor nodes goes up to 256.
-	Added initial support for devices that have more than one port.
-	Added more debugging comments for the Visor, and added a needed
-	set_configuration call.
-
- (01/17/2000) gkh
-	Fixed the WhiteHEAT firmware (my processing tool had a bug)
-	and added new debug loader firmware for it.
-	Removed the put_char function as it isn't really needed.
-	Added visor startup commands as found by the Win98 dump.
-
- (01/13/2000) gkh
-	Fixed the vendor id for the generic driver to the one I meant it to be.
-
- (01/12/2000) gkh
-	Forget the version numbering...that's pretty useless...
-	Made the driver able to be compiled so that the user can select which
-	converter they want to use. This allows people who only want the Visor
-	support to not pay the memory size price of the WhiteHEAT.
-	Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
-	grabbed the root hub. Not good.
-
- version 0.4.0 (01/10/2000) gkh
-	Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
-	device. Added startup function to allow firmware to be downloaded to
-	a device if it needs to be.
-	Added firmware download logic to the WhiteHEAT device.
-	Started to add #defines to split up the different drivers for potential
-	configuration option.
-
- version 0.3.1 (12/30/99) gkh
-      Fixed problems with urb for bulk out.
-      Added initial support for multiple sets of endpoints. This enables
-      the Handspring Visor to be attached successfully. Only the first
-      bulk in / bulk out endpoint pair is being used right now.
-
- version 0.3.0 (12/27/99) gkh
-	Added initial support for the Handspring Visor based on a patch from
-	Miles Lott (milos@xxxxxxxxxxxxxxxxx)
-	Cleaned up the code a bunch and converted over to using urbs only.
-
- version 0.2.3 (12/21/99) gkh
-	Added initial support for the Connect Tech WhiteHEAT converter.
-	Incremented the number of ports in expectation of getting the
-	WhiteHEAT to work properly (4 ports per connection).
-	Added notification on insertion and removal of what port the
-	device is/was connected to (and what kind of device it was).
-
- version 0.2.2 (12/16/99) gkh
-	Changed major number to the new allocated number. We're legal now!
-
- version 0.2.1 (12/14/99) gkh
-	Fixed bug that happens when device node is opened when there isn't a
-	device attached to it. Thanks to marek@xxxxxxxxxxxx for noticing this.
-
- version 0.2.0 (11/10/99) gkh
-	Split up internals to make it easier to add different types of serial
-	converters to the code.
-	Added a "generic" driver that gets it's vendor and product id
-	from when the module is loaded. Thanks to David E. Nelson (dnelson@xxxxxxxx)
-	for the idea and sample code (from the usb scanner driver.)
-	Cleared up any licensing questions by releasing it under the GNU GPL.
-
- version 0.1.2 (10/25/99) gkh
- 	Fixed bug in detecting device.
-
- version 0.1.1 (10/05/99) gkh
- 	Changed the major number to not conflict with anything else.
-
- version 0.1 (09/28/99) gkh
- 	Can recognize the two different devices and start up a read from
-	device when asked to. Writes also work. No control signals yet, this
-	all is vendor specific data (i.e. no spec), also no control for
-	different baud rates or other bit settings.
-	Currently we are using the same devid as the acm driver. This needs
-	to change.

-	<udo.eisenbarth@xxxxxx> for the information.
-
- (02/27/2002) gkh
-	Reworked the urb handling logic.  We have no more pool, but dynamically
-	allocate the urb and the transfer buffer on the fly.  In testing this
-	does not incure any measurable overhead.  This also relies on the fact
-	that we have proper reference counting logic for urbs.
-

-  Added initial support for the Palm m515 devices.
-
- (02/14/2002) gkh

-	for CliĂŠ devices that lie about the number of ports they have.
-
- (08/30/2001) gkh
-	Added support for the Clie devices, both the 3.5 and 4.0 os versions.
-	Many thanks to Daniel Burke, and Bryan Payne for helping with this.
-
- (08/23/2001) gkh
-	fixed a few potential bugs pointed out by Oliver Neukum.

-
- (04/08/2001) gb
-	Identify version on module load.
-
- (01/21/2000) gkh
-	Added write_room and chars_in_buffer, as they were previously using the
-	generic driver versions which is all wrong now that we are using an urb
-	pool.  Thanks to Wolfgang Grandegger for pointing this out to me.
-	Removed count assignment in the write function, which was not needed anymore
-	either.  Thanks to Al Borchers for pointing this out.
-
- (12/12/2000) gkh
-	Moved MOD_DEC to end of visor_close to be nicer, as the final write
-	message can sleep.
-
- (11/12/2000) gkh
-	Fixed bug with data being dropped on the floor by forcing tty->low_latency
-	to be on.  Hopefully this fixes the OHCI issue!
-
- (11/01/2000) Adam J. Richter
-	usb_device_id table support
-
- (10/05/2000) gkh
-	Fixed bug with urb->dev not being set properly, now that the usb
-	core needs it.
-
- (09/11/2000) gkh
-	Got rid of always calling kmalloc for every urb we wrote out to the
-	device.
-	Added visor_read_callback so we can keep track of bytes in and out for
-	those people who like to know the speed of their device.
-	Removed DEBUG #ifdefs with call to usb_serial_debug_data
-
- (09/06/2000) gkh
-	Fixed oops in visor_exit.  Need to uncomment usb_unlink_urb call _after_
-	the host controller drivers set urb->dev = NULL when the urb is finished.
