With a bit of luck it's sufficient to add the USB IDs in snapscan.conf 
and edit the path to the firmware file in snapscan.conf. The firmware 
file is installed with your windows driver, it's probably named *.bin 
and located somewhere under WINNT/Twain32.

If possible please send me a debug log from 
"SANE_DEBUG_SNAPSCAN scanimage -L > debug.log"
