I'd you install the drivers before you plugged in the mouse?
The mouse should work without any drivers as its a plug in and play device.
However my cyborg keyboard has a mind of its own, when booting the bios says no keyboard detected even though it is and works fine.. But only on 1 usb port, the rest it doesn't even power up on, so ill suggest changing ports as well. My rat 9 has been faultless though
