Yes you were right... I disabled all USB stuff in setup bios, and the "long tasks" disappeared in my test program! No more 270 or 400 usec task.
I thought USB was also handled by interruptions, but as RayeR says it's different way.

So now I just have "small" tasks left, which happen about 18 times per seconds, so it must be linked to the clock. It goes from 15 to 40 usec, depending on computer, which is quite a difference.

In your opinion, is it a matter if I inhibit this time interrupt ? I mean permanently, as long as my program is running...
