     Hello,

     development on the genesys backend is a mix of reverse engineering 
(through usb logs capture) and  use of the few known docs on genesys 
chips. It close to impossible, or a least *REAL* slow to develop support 
for a scanner without having one to snoop usb data and test code.
     If you have a windows set-up where you can record USB activity 
(preferably with usbsnoop), please send me a log recording a color 
preview. That way we well double check it is a genesys based scanner, 
and I'd be able to evaluate the amount of work involved.

Regards,
     Stef
