     so this scanner can be added to the genesys backend in the 
genesys_gl841.[ch] files (which in fact supports mainly GL842 based 
models). However the reported resolution of 7200 doesn't match the 2400 
max resolution for the GL842 chip. Some custom sensor interleaving like 
for the gl847 devices ?
     Another hurdle is that no 2400 dpi support is done for this kind of 
chip. I'm afraid this won't be trivial.

     Do you think you can record an usblog of a preview scan ?
