Sometimes when I start my computer, my wireless mouse doesn't respond. For the longest time I thought it meant the battery was dying so I'd replace it. Eventually I realized that if I just unplug and plug back in the USB transmitter/receiver that is connected to my computer, the mouse responds and works fine. It's annoying have to reach behind my computer every time this happens, so I was wondering if anyone knew of a way to do some windows command that reinitializes all USB devices. Any help is appreciated!
