Weird problem with laptop and USB mouse

I don't quite understand - CPU usage is a percentage, so how can the system idle process be close to 100 & the CPU usage at 80?

Beats me! That's the weird thing, I'll se if I can get a screenie later..

And what were you doing before you took that CPU usage pic? Your CPU is spiking a bit, but it's not permenantly high?

I was opening an internet explorer window somewhere around the start which I closed again, and I was typing some on IRC..

And the mouse gets laggy and network connections drop out

It varies how it behaves when I take out the mouse, but laggy mouse and network dropouts are there no matter..

Here's another picture, I pulled out the mouse where it starts going high, and I did nothing but looking at the task manager untill I plugged it back in..
