I tried with oneiric live on usb for more than 10 days without reproducing. I figured out that the issue pretty occur on colds boots (and resume from suspend/hibernate). I never had the issue again in precise while it was booted by restarting from oneiric. Then, after finishing the oneiric testings, when the problem occured in precise i tried to restart instead of unplugging and it worked too.
Then i ran new tests with latest saucy live : It never works, even unplugging several times.
