Comment out the last line. If you used uscanner, you would have to add
/dev/uscanner0 here. But with libusb, it's not neccesary (and wrong).

Your libusb is too old. 0.1.8 is minimum, 0.1.10a is current. I'll add
that version number to the SANE README, which currently says 0.1.6.

Yes. Not for your backend, but for others.

This does not work. Don't list the ugen devices directly. When libusb
is found by sane, the device will be detected automatically.

I think that's ok. libusb knows about the exact device names.

No.

"-v -v" turns on maximum debuging for sane-find-scanner. You can add
debugging for the sanei_usb code by doing 
"setenv SANE_DEBUG_SANEI_USB 255" but this won't really help.
