If I leave the computer and let it run into screensaver and lock the screen, the mouse left click won't go back to work. If I suspend the computer, the keyboard won't get back to work. It started after upgrading to Ubuntu 11.04. Any tips to solve this problem?

The follwing lines I got on dmesg after the problem happened

and that after I tried to plug again my USB mouse:

well... I updated to the kernel 2.6.38-9 and I guess it is working fine now... –  LEo May 3 '11 at 19:11
