Hi all,

I have a problem on my XPS-12 with ubuntu 12.10 boot on it after launching "sudo apt-get install linux-backports-modules-cw-3.6-3.5.0-40-generic" command and reboot: USB are not working anymore. I have no idea of how to fix the problem...
For information, my wireless stopped working and "sudo modprobe iwlwifi" (the driver) did not make any change. I looked to threads on google that lead my to try blindly the backport install command.

Any clue ?
