Hi, i have a NAS DS213 from synology and this nas has connected a usb printer F2180.
Synology shows a fully supported printer with scanner.

printing works fine, but the scanner does not work.

# sane-find-scanner will now attempt to detect your scanner. If the

found USB scanner (vendor=0x093a, product=0x260e) at libusb:002:003
# 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.


scanimage --list-devices
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).




I hope someone can help me get the scanner running.
I have installed simple scanner, which does not scan too. i tried with sudo too, no luck.
