[sane-devel] CanoScan LiDE 220 can't scan dpi over 1200

[Aaron Muir Hamilton]

Hmm, can confirm, it scans some portion of the image and then hangs. I
think the official software on Windows doesn't support full-page scans
at 2400dpi or greater. It does work if you limit the scan to an area.

Not sure what should be done about this, I don't think there's a
standard way to expose constraints like this to scanimage (but I'm not
sure!).
