My Genius ColorPage Vivid4 USB scanner worked acceptably under Windows, so it was the time to get it working with SANE.
Running (as root) sane-find-scanner, it said:
found USB scanner (vendor=0x0458, product=0x2014 [600DPI USB Scanner], chip=GT-6816) at libusb:003:004
However, it does not run with xsane just out-of-the-box:
No devices found
The SANE page for these category of scanners is www.meier-geinitz.de/sane/gt68xx-backend, and the important part of what's written there is:
Genius Colorpage Vivid4 0x0458 0x2014 ccd68861.fw Works.
Now, where to find ccd68861.fw firmware?
