Hi,

I have an external Pioneer DVD writer which I connect via Firewire to my
laptop. So when I turn it on I get this in my dmesg:

drivers/usb/input/hid-input.c: event field not found
ieee1394: Error parsing configrom for node 0-00:1023

~ Vendor: PIONEER Model: DVD-RW DVR-105 Rev: 1.20
~ Type: CD-ROM ANSI SCSI revision: 02
Attached scsi generic sg2 at scsi2, channel 0, id 0, lun 0, type 5

Problem now is, that it stays on /dev/sg2. There is no more mapping. The
output of sg_map is this:

pluto:~# sg_map
/dev/sg0 /dev/sda
/dev/sg1 /dev/sdb
/dev/sg2

[sg0 is the internal Sony Memory Stick reader, sg1 is an external Maxtor
200 GB Firewire HD]

So is there anything wrong with hotswap? or which part doesn't make the
connection from sg2 to any cd device. The problem is, which just sg2 I
(as user) can't do much as sg2 is just root rw ...

lg, clemens
