I have an Asus K8N-E motherboard and a Microsoft Intellimouse Explorer 4.0A. When booting up in Windows XP, the mouse does not work. If I unplug it from the USB port and plug it back in, it works.
I have tried another Microsoft Optical mouse, and reloaded the OS from scratch a couple of times. I haven't installed any mouse drivers either.
Any idea's what could be causing this as it's driving me mad !
