[sane-devel] Visioneer OneTouch 7100 USB

[Mark Adams]

Okay, I renamed the sane ver. 1.0.20 executibles in /usr/bin and created 
soft links to the ver. 1.0.21 executables in /usr/local/bin.  Now, 
"scanimage -d genesys:libusb:007:003 >image.png" run as root produces a 
black and white image.  Huzzah.

Unfortunately, I still can't get a frontend to find the scanner and open 
successfully. Should I be able to configure Xsane to work with this?  If 
so, could someone possibly toss me a clue as to how?

Thanks.

Mark
