[sane-devel] Canon LiDE 210 and grinding noises

I have similar problems with my Canon LIDE 220. Please see the thread I 
recently started entitled "Canon LIDE 220". Bottom line is I get it to 
work very well using USB3 by setting the environment variable


Disabling USB3 may be another way of masking a race (timing) problem. 
Maybe the same problem for both models? I'm a retired sys admin and not 
so strong on programming so maybe you can do better than me messing with 
the code.
