Hi, I can confirm that this bug entered testing sometime between 2009/12/02 and 2009/12/08.
On 2009/12/08 I ran an update and after the next reboot the mouse pointer did not move anymore (standard USB Dell Optical Mouse), neither in X or in console with gpm, and /dev/mice, /dev/input/mice, /dev/psaux were empty when I moved the mouse. The previous update was on 2009/12/02. I have attached the commit log from Synaptic. As you can see from it the kernel was not updated, so I am unsure this bug should be filled against the kernel. My guess is it could come from hal, which was updated. But perhaps is it not so obvious. Sorry for the delay in commenting on this bug, I was busy and then away from work (problem happened on my work computer). Unfortunately I cannot provide any extra feedback as my IT department changed my mouse for a Logitech one that is still recognized. Good luck for fixing. Yann Yucov
