Yes, X11/DM, logged locally on the "physical" console.  Thanks for the 
hint on automount.

Thanks for your help Frank.

The problem i have is that it won't necessarily be the same devices 
plugged to this box and the user could even plug many devices at the 
same time.

So i read many articles on the net but i'm kinda lost about where to 
start for this problem.

Anyway, i'm still reading an thanks again for your help!
