     Well,

     I can't say for now. Currently the backend doesn't tune gain and 
offset on the analog frontend, maybe it is needed now, this is why a log 
would be great.
     Since you have good quality scans with windows driver, there is 
something to improve in the genesys backend.

Regards,
     Stef
