I had to replace my motherboard... that's solved also my problem.
I don't know if both problems ( bug "device missclassified" and hardware problem ) were linked. I think probably not, but it is not impossible either that the new kernel destroyed my moteherboard, either that an an hardware weakness was responsible of the bug )
Everything works fine for me now with my ASUS P5 KPL-CM. (no other changes)
