Description nucleo 2012-06-16 16:05:02 EDT
Description of problem:
"Microtek ScanMaker 3840 flatbed scanne" detected by sane-find-scanner but not identified by "scanimage -L"

Version-Release number of selected component (if applicable):

How reproducible:
every time

Actual results:
$ 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.

found USB scanner (vendor=0x067b, product=0x2303) at libusb:003:002
found USB scanner (vendor=0x05da, product=0x30d4 [USB Scanner]) at libusb:003:004
  # 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.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.

$ 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).

Expected results:
scanimage output should be the same as in Fedora 16:
$ scanimage -L
device `sm3840:libusb:003:003' is a Microtek ScanMaker 3840 flatbed scanner

Additional info:
No such problem in Fedora 16 with the same kernel and sane-backends
sane-backends-1.0.22-10.fc16, kernel-3.3.7-3.fc16.i686

Your Fedora 17 installation is missing the sane-backends-drivers-scanners package, please install it.
Comment 4 nucleo 2012-06-18 14:40:50 EDT
Thanks, scanner works after installing sane-backends-drivers-scanners.
