Sorry for the late response, but the mail mail was delayed until today.
Since you have read the archive: The problem with the wrong colors is related to the "bytes_per_line should be 3 * pixels_per_line, but it isn't" problem.
Other users have reported exactly the same misbehaviour (wrong colors) for the version that works for you. I am currently trying to collect a list of models and FW versions to elaborate the circumstances, under which this behaviour is shown.
Thus it would be interesting, which FW version and model code your device has.
Also, there exists an update of the backend on
ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.280399.tar.gz .
If you like, you can try it and tell me the results. I would be interested, if it works for you or if the colors are wrong again.
In any case: I know now where the problem is and can provide a patch, if necessary.
