I hope someone can help out with this very annoying problem. Recently my usb mouse has been disconnecting itself at random times. If I unplug then re-plug it starts working again but the problem still persists. I tried the back and front usb jacks but it didn't help in solving the issue. I'm using Win 7 64 and a R.A.T. 7 gaming mouse. Thanks to anyone who can offer some advice.
