Same problem, in my case with a USB-attached Canon Canoscan N650U (an
ancient, well supported scanner, that was working just fine on
12.04LTS).

/lib/udev/rules.d/40-libsane.rules looks like it ought to be detecting
it ...
$ cat /lib/udev/rules.d/40-libsane.rules | grep 2206
ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="2206", ENV{libsane_matched}="yes"
But I get nothing created in /dev ...
And trying to search for the scanner produces no results, though some
slightly odd looking intermediate debug information:
$ sudo SANE_DEBUG_SANEI_USB=255 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.

Title:
14.04 won't detect common USB scanner
Status in “sane-backends” package in Ubuntu:
Confirmed
Bug description:
My multifunction Samsung SCX3200 printer is not detected by sane, but
printing is fine. This scanner is faily generic and supported out of
the box by the Xerox MFP driver (sane default).

Problem: sane-find-scanner can't find the scanner:
--------------------------------------------------------------------------------------------
$ sudo sane-find-scanner -q
$ (no output)
$ sudo 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).

Simple-scan will just show a "Unable to start scan" error.
Also tried:
- Running simple-scan and xscan as root
- Adding myself to lp, saned and scanner groups, then log off + log on
- Power cyling the printer, disconnected and plugged back in
- Switching USB port (USB2 <-> USB3)
- Restarting the udev service
This scanner is faily generic and is supposed to be working OOTB since 12.04:

I think this may be a bug with libsane.
