I have a similar problem on a Dell Latitude E4310, and it appeared around the same period (december 2010): my USB cordless mouse stopped working intermittently, and plugin it out and back in does not always solve the problem.
I attach a fragment of /var/log/syslog where at 09:29:06 I plug the USB receiver and the mouse works, and then at 09:29:24 the mouse stops working, with a lot of USB errors in syslog. later on, at 09:34:41, I plug the receiver again but it is not even recognized Some info: p...@nua:~$ lsusb Bus 002 Device 035: ID 046d:c52f Logitech, Inc.
