[sane-devel] Webcam-like book scanners

[m. allan noah]

Fujitsu also makes a similar scanner. It has an integrated USB hub, and
shows up as multiple devices behind that hub. I've never been successful in
properly initializing the device. Even if I was, it won't be easy to
convince the SANE USB library to let me control three devices at one time.
I expect these kind of scanners might be better off with a standalone
program.
