Thanks! I already started to wonder if I was the only one in the whole 
world that had any interest in getting this old scanner to work :)
(On a serious note, I do understand that you are a busy person, and also 
that more common scanner models (affecting more users) have to get higher 
priority.)

Yes, I understand the problem.
Another thing I'm wondering is if it would be possible to give the scanning 
process and the pt_drv module a higher priority, but that question is so 
obvious that I'm sure that you have thought of that before and have your 
reasons for not going that route.
(I tried to renice the xscanimage process, but that didn't help -the 
communication is done on a lower level?)

Thanks!
