repos. Still no improvement.
So I activated trusty-pr

Sorry for spamming, but my previous patch was still guesswork and worked
only with a single resolution.
This new patch now uses values from scanner responses and seems to be
fully functional. Enjoy.

Maarten's patch wasn't working for me, but I've debugged the code and
figured out the remaining issues. A patch is attached.

Actually, I think this issue is pretty bad as it will make me return my
hardware.

Obviously, RAW scanning is completely disabled on purpose. In ledm.c I
found the following in function set_scan_mode_side_effects:

Btw, if this is SW fixable, I'm willing to help, but I need some
pointers what to do.
