seems debian did some strange things i don't understand. Finally build
the whole package anew and installed it, otherwise(with the way
described, same version as the installed package) the scanner would not
be recognized.

Well, it didn't work. The black bar at the top of the back side is
still 70px, the one on the bottom of the front side grew up to 140px.

kind regards,
