Hi,

Following the status-update posts I'm not quite clear about the status 
of the gl841 part of the backend. Does it do s.th. yet and are scanners 
with
that chipset already supposed to be recognized? I checked out the 
experimental cvs code and tried both genesys and genesys-new, but despite
sane-find-scanner detected my CanoScan Lide 80 and the chipset, it does 
not get listed by scanimage -L.
Could one of the devs please post a short gl841-specific status report 
so I know what the backend is supposed to do?
Thanks a ton for your work on the backend!!

Best,   Nick.
