you have a couple options:

1. attempt to dis-assemble the windows driver (pita)
2. open the scanner and see if any of the numbers on any of the chips 
sound like a supported scanner (fat chance)
3. get packet logs from scanner running on windows, and hope it uses a 
higher level protocol like scsi over the usb (pita, and fat chance :)

search on the sane mailing list archives for reverse engineering and 
backend writing, this gets discussed quite a bit.


ps p.i.t.a. is short for pain-in-the-butt for all the non-native english
