I can't even get "scanimage -L" to find the device as root: 


    bash # sane-find-scanner

    found USB scanner (vendor=0x04b8, product=0x010f) at /dev/usb/scanner0
    found USB scanner (vendor=0x04b8, product=0x010f, chip=LM983x?) at libusb:001:002
      # Your USB scanner was (probably) detected. It may or may not be supported by
      # SANE. Try scanimage -L and read the backend's manpage.

    bash # 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).


so I'm sceptical about this being the source of the problem.  

Thanks,
