I cannot comment on the subject from own experience, but I trust you guys 
on this. To what you have said, I could add that the original 
author/maintainer of this code is sadly not arround anymore. I would like 
to hear some input from Axel and Ingo though, since they seem to be most 
familiar with the code of the device manager.
