My Logitech Anywhere MX Mouse (Unifying Receiver) is no longer recognized automatically.

On 10.04-12.04, I had no problems. I installed edubuntu-desktop on top of plain Ubuntu 12.04 and now when my computer starts with the USB receiver plugged in, the USB mouse doesn't work. The touchpad works and if I unplug the Unifying receiver and plug it back in, the USB mouse then works fine again.

Any ideas? Will 'sudo apt-get purge edubuntu-desktop' revert back and fix everything?

Thanks for the help
