i recently did an update (march 9th 2012) and after rebooting the system all USB devices aren't working anymore.
I get the following message in /var/log/syslog when i plug in my mouse or keyboard
I'm using Ubuntu 11.10 on a Dell Vostro V131
Mar 9 10:19:37 steib kernel: [ 1129.756345] usb 3-1: new full speed USB device number 10 using xhci_hcd

Mar 9 10:19:38 steib kernel: [ 1130.163803] usb 3-1: device not accepting address 10, error -71
I hope someone can help me.
best regards and thanks,
