Problem with mass storage usb devices

[Sébastien Morand]

Hi,

I get a problem with usb mass storage device.

Everytime I plug my camera or my mp3 player, my system hang up a few seconds and 
then reboot. The two devices are fine and running well under WinXP or Linux. (on 
the same computer about linux)

The two devices are USB 2 capable and I have two other devices (key usb and usb 
hard disk) which are running fine.
