I see. Is this used in the code anywhere? To which value should I set
it?

Ok, I will look into this later. What about the Scannermodel entry?
Ist this just the name or does this have influence on scanning?

The Mustek BearPaw 1200 now also works. Color mode is quite ok, gray
mode has stripes sometimes. Binary doesn't work at all. Resolutions
are as above (75-600 dpi). Preview freezes the scanner because at 50
dpi the motor doesn't move. This time the values are from the Mustek
source code so I'm more confident with them :-)

Here is the data:

Some information including a sane snapshot with these changes is at

try ...
