OT - Please Help with sane / scanner

[kevin.kempter at dataintellect.com]

Hi List ;

I bought a Plustek OpticSlim M12 sheetfeed usb scanner.
If I run sane-find-scanner I see the following:
found USB scanner (vendor=0x07b3, product=0x0412 [600dpi USB Scanner], 
chip=GT-6816?) at libusb:002:004
  # Your USB scanner was (probably) detected. It may or may not be supported 
by
  # SANE. Try scanimage -L and read the backend's manpage.

However if I run scanimage -L I get this:
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 dont know where to go from here...

Thanks in advance for any help
