Summary:
Canon CanoScan LiDE 120 maximum scan height

Detailed description
As instructed by the PROBLEMS file, I'm here to report that CanoScan LiDE 120 (listed in http://www.sane-project.org/lists/sane-mfgs-cvs.html ), when tested with the latest git version of sane-backends, seems to be used with wrong height, producing bad noises and whatnot.

This might be related to my using USB 3 ports (I had no USB 2 to test with).

More details follow (yes, I had to use sudo so probably I had some permission issues, didn't bother to fix those but should be unrelated).

I checked and the device code was only listed in the genesys config, but I also tried and disabled the various canon backends in case they were interfering, so it ought to be genesys.

Hi Gerhard,

I'm assigning this to you since you're the last developer around that has experience with the genesys backend. Any ideas?

If not, you may try assigning to Aaron as has mentioned having a 220.
