Hi:

 I tested the latest source and it seems to work OK. USB scanning works.
However when i start multiple sessions of Octave, a MatLab clone, and have it 
do huge computations it crashes my Kde 3.1.3 desktop because the computer has 
run our of swap space. This did not happen in 4.8. If the machine ran out of 
swap space in 4.8, it just killed the offending application.

Here is an excerpt from /var/log/messages:

 I had a Gnome desktop running on display :2  and it did not crash.
