sensor signal to the one a CCD-chip might send to the genesys chip. Thus, I 
believe the best solution might be to emulate one of those chips from the 
communication side. Since we are going to use a FPGA for other purposes 
already it might be the "easiest" way to emulate the communication between 
the PC and the scanner chip such that the sane-backend resp. Twain-driver 
still believes a normal scanner is connected. 
Is there one IC with a wide usage or something like a reference IC? Is there 
any kind of standard protocoll, which we might can follow?  Which manufacture 
provides most information? And which one welcomes projects like this (resp. 
opensource in general) without let the dogs resp. lawyers out.

Many thanks for your help
