[face=Sans-Serif][/face][color=purple][/color] The issue started up again. Basically, the light goes out on the mouse and then it will sound off and then on. If it doesn't go back on, I've been plugging into another USB port. Then it's fine. The USB ports and the mouse are in working order, according to my Device Manager. I tried to update the driver but there weren't any updates. Once during the on and off, the driver was re-installed. When I uninstalled it at a port, it didn't automatically re-install. But the mouse still worked.
I don't have a mouse icon in my tray so the mouse has been going on and off without any safe removal. This happened with my digital camera too at its usual port. I went to another port and when I went back to the one that didn't work, it worked fine.
It's musical chairs with my USB ports. I don't understand why the drivers don't re-install if I uninstall and why the port still works. It's every few days, there's a disruption, easily fixed but, as you say, it could be damaging the ports. In the troubleshooting, I read that there could be a power problem with too many ports being used. I use a digital camera at one, a printer at another. Is it overload?
