Public bug reported:
Using Ubuntu 13.04 with latest patches
Hardware : Asus N56V laptop
when disconnecting power supply and running on "battery"
the usb mouse will loose it's current after 20s with only the touchpad working
disabling the touchpad only gives me "keyboard" support
reconnecting the mouse in another usb port will give me a few seconds of mouse
activity...then the laser inside will go down again...
