simple-scan:
if i plug it in it finds it but does not scan; on the first pass. after it exits, it does not find any scanner until i physically re-plug it in.

lsusb shows the scanner all the time while it is plugged in

i replaced the scanner with the logitech to see if the plug work without rebooting.. and the mouse works fine.
the snapshot was with the logitech plugged in.

Title:
  scanimage -L finds fitjitsu 04c5:11fc but if repeated does not find it

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Using my System76 gazel, with a fully updated Ubuntu GNOME 14.04, my
  Fujitsu  6110 Scanner doesn't work via either USB 2.0 or 3.0.

  if i re-plug it and type:
  scanimage -L
  device `fujitsu:fi-6110dj:28760' is a FUJITSU fi-6110dj scanner
  scanimage -L

  No scanners were identified. If you were expecting something different,
  check that the scanner is plugged in, turned on and detected by the
  sane-find-scanner tool (if appropriate). Please read the documentation
  which came with this software (README, FAQ, manpages).

  Re-plug it back and type:
  scanimage
  scanimage: open of device fujitsu:fi-6110dj:28760 failed: Error during device I/O

  while I'm getting the error on scanning, I'm not sure this is a usb2 usb3 xhci_hcd issue as per dmesg:

  even though a 'no find scanner' after the error the lsusb above
  remains the same.

  WORKAROUND: The scanner works perfectly on a USB 2.0 port in Ubuntu
  12.04 system with no driver added.
