We have few USB scanners Canon DR-3010C which for some reason do not work under SLED (sled11sp2x64).

sc02:~ # 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.

  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.
And in /var/log/messages you can see:

All looks fine, however:
Code:
sc02:~ # scanimage -d canon_dr:libusb:002:002 -v
scanimage: sane_start: Invalid argument
Xsane gives out the same error.

Any ideas?

Code:
sc02:~ # rpm -qa | grep sane
