Thanks again Jan.

Another point; for RT USB developers, do you think we could use Linux 
native USB stack with PREEMPT_RT in the same way as Xenomai / USB4RT ?

I'm pleased with this last solution but the USB4RT bug (need to send a 
command twice) is a real problem for performances (i'd like to increase 
my acquisition rate within a fixed cycle). My only approach to real time 
for the moment is USB driver, and in the Open world i cannot find what 
could be the "right" or "best" solution...
