Regarding USB-serial device driver

[Raju Rameshwar Uprade]

Hi Greg,
               I have a UART device  driver which is used to control some  MCM ( Monitor
& control module ) devices with  address like 2,3,5,10,14 & 0 thru serial port using
RS-485 interface card.

Now I want to control these devices thru usb-serial adaptor card.When I plug the
usb-to-serial device.It's shows me the terminal ttyUSB0.

I tried sending data thru it , but in between some junk data is also going out ....

output of usbmon :

Ideally data which should go out is : 0080000000f8.( device address is 0 and check sum
is f8 ).

In my  previous emails, you told me to use current kernel version..so I am now using
2.6.35 kernel version.

 kindly help me.


Thanks-
 Raj.
