[sane-devel] Big problem with fi-5650c under linux

Sat Apr 14 08:42:41 UTC 2007

Hi Allan,

Thank you and Juan Pablo Mendoza for your work. I have obtained the 
latest cvs snapshot and the scanner works fine on scsi now: color, 
double sided, everything that I tried is ok.

The erroneous pixel shift is also gone. Kudos!

I would like to confirm the USB operation, but I am not familiar with 
USB. You can find some of my futile attempts below. SCSI is removed from 
fujitsu.conf, some USB settings added. Did I miss anything?

The machine will be with me for a few more days, so let me know if there 
is anything I can do to help test.

Greets,
Guus.
