Public bug reported:
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).
Printer/scanner as seen by the kernel, device 007 : ID 04e8:3441

The IDs are properly set in udev and sane.d configuration:
--------------------------------------------------------------------------------------------
$ cat /lib/udev/rules.d/40-libsane.rules | grep 3441
ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="3441", ENV{libsane_matched}="yes"
$ cat /etc/sane.d/xerox_mfp.conf | grep 3441
usb 0x04e8 0x3441
--------------------------------------------------------------------------------------------
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).

The kernel module is properly loaded when the printer is connected, no
blacklisting :

$ sudo lsmod | grep usblp

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.
