Can you both play with the msleep in dib0700_core.c:232 ? It is already at 
500ms (normally it should be 100ms) .

Releasing the specs to everyone would not help in this situation, because 
the problem which is seen by some of you is very specific to Linux/the 
Linux-driver. So far I have no real clue what it is. Maybe the msleep is 
not delaying things as its call claims to...

I'm trying to find some time soon to get into this issue.

Patrick.
