[sane-devel] Canon Canoscan N1220U not working on Mint 16 after latest update.

[Eli Ren]

I have a Canon Canoscan N1220U that stopped working on my office computer a
couple months ago after an update (running Mint 16 Cinnamon).  I had
intermittent issues with it not working in the past, sometimes having to
unplug the scanner or re-start the computer, depending on which OS I had
installed at the time (various Ubuntu or Mint installations), but now I
cannot get it to work at all.  I tried plugging the scanner into one of my
other machines (running mint 13 MATE) and it works just fine (works with
simplescan, xsane, and sane-find-scanner gives the expected output), so I
know it's not an issue with the scanner, cord, or USB port (I tested
multiple USB ports with several devices and the scanner is the only device
not playing nice).  All updates are current (all stable releases).

I'm hoping someone on here might be able to help get this working with my
desktop computer again.  I would really appreciate any insights you might
have.

Thanks,
