Comment 0 for bug 879619

After upgrading to 11.10, the scanner does not work anymore (the printer is fine in the 32 bit version of Ubuntu using Samsung's unified drivers).
I have added the configuration for SCX-3200 as shown here:
http://3v1n0.tuxfamily.org/tumblelog/post/936/
but nothing changed.

Output of diagnostics:

  # 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

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

  # found the scanner devices, be sure to adjust access permissions as
  # necessary.

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).
