My USB MS Intellimouse Explorer continuously goes on and off. Has anyone else had problems with USB devices on their system, or this mouse in particular with XP?

mine would go off and on/redetect every now and then so i went back to the ps2 port. :(

I've had similar problems with both IntelliMouse Explorer and the regular IntelliMouse Optical. In all three cases (not all my own mice) it was a soldering issue resulting in a loose connection between the cable and the point at which it was fixed to the print board inside the mouse.

I have a usb intellimouse and I have no problems...try looking for the latest drivers on the microsoft site or get the new sp1 for XP that's out.

I was wrong above, it's a problem with the small wires inside the mouse cable. After some us, typically over a year (which conveniently coincides with the expiry of the warranty) one or more of the have broken due to metal fatigue. I know because I just got another one and on closer examination it turned out that it was a broken wire inside the cable.

Thanks for the suggestions people....
Fixed it by installing a USB addon card.
Works fine now...Lucky I repair and sell PC's for a living as I am able to aquire free parts [img]smile.gif[/img]
If I had to pay for it I would have been pi**ed.
