Last modified: 2012-06-18 14:40:50 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):
# 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.
# 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
$ 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).
scanimage output should be the same as in Fedora 16:
$ scanimage -L
device `sm3840:libusb:003:003' is a Microtek ScanMaker 3840 flatbed scanner
No such problem in Fedora 16 with the same kernel and sane-backends
Created attachment 592352 [details]
strace output for "scanimage -L" in Fedora 16
Created attachment 592353 [details]
strace output for "scanimage -L" in Fedora 17
Your Fedora 17 installation is missing the sane-backends-drivers-scanners package, please install it.
Thanks, scanner works after installing sane-backends-drivers-scanners.
