[Ganton <1214319@xxxxxxxxxxxxxxxxxx>]

It also happens to me in a laptop, although the mouse and keyboard don't completely freeze, sometimes they work so slowly that it looks that they have frozen. 
        
I've got a CPU monitor in the screen, and when the almost-freeze happens, the CPU monitor doesn't show any increase in the CPU usage, if I use the "top" command it also doesn't show any high usage of the CPU, the "hard disk led" doesn't show any activity, .

I've got Kubuntu 11.04 in another partition, and if I boot with it, that
problem never happens.

Title:
  046d:c52b USB Mouse and keyboard freezes randomly but often

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Using UBS mouse and/or keyboard let my Ubuntu freezing very often. Not
  everytime it occures, but quite often. Then only a reboot is possible.
  Also, when Ubuntu freezes, only the usb is affected. So actually
  ubuntu is still working, but the usb system is off. There is also not
  a single event about that in the kernel log.
