Bug 1761234

Description of problem:

scanimage doesn't list Canon LiDE 110 scanner anymore even though sane-find-scanner lists it:

$ sane-find-scanner 

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

I used this scanner with simple-scan on this very same install a month ago, so the driver should work. Now neither simple-scan nor scan-image list it anymore. (Was the driver taken out with a recent kernel update or something?)

Version-Release number of selected component (if applicable):
scanimage (sane-backends) 1.0.28; backend version 1.0.28

How reproducible:
100%

Steps to Reproduce:
1. Plug in Canon LIDE 110
2. Run scan-find-scanner which lists scanner
3. Run scanimage -L which doesn't
3. Open simple-scan which also no longer lists it

Actual results:
in the actual scanning programs scanimage and simple-scan I can no longer use the scanner

Expected results:
scanner is still available

Additional info:
I renamed my user recently with usermod -l, which might or might not be related. However, sudo'ing scanimage does nothing and my new user is in the "lp" group, so I'm not sure what permissions are off if any
