Hello, I have a Canon LiDE 210. The sane-website says it is supported ?Complete? by sane-genesys.
It can scan at resolution up to 4800dpi, but the stable version of sane (1.0.22-7.1 from debian wheezy) treats it as a Canon LiDE 200 and only offers resolutions up to 1200dpi which works fine. I installed the git-snapshot of the backends and with this version sane offers resolutions up to 4800dpi, but the resolutions above 1200dpi (2400dpi and 4800dpi) do not work at all. It has to be aborted by 2 times Ctrl-C: 18 hermione:/tmp/sane [09:04:29] > bin/scanimage -d genesys:libusb:001:005 --resolution 2400 > X.png ^Cscanimage: received signal 2 scanimage: trying to stop scanner ^Cscanimage: received signal 2 scanimage: aborting 19 hermione:/tmp/sane [09:04:58] MfG bmg -- ?Des is v?llig wurscht, was heut beschlos- | M G Berberich sen wird: I bin sowieso dagegn!? | berberic at fmi.uni-passau.de (SPD-Stadtrat Kurt Schindler; Regensburg) | www.fmi.uni-passau.de/~berberic
