Every once in a while my USB mouse, which is plugged into a 7-port externally-powered hub, stops mousing. If I unplug it from the hub and plug it directly into one of the USB ports on the computer, it immediately starts working again. If I plug it back into the hub, it doesn't work. Other peripherals plugged into the hub continue to work (empeg, Karma, camera, scanner, printer, ipod) but not the mouse. Plugging the mouse into one of the other hub outlets does not make it start working. Rebooting the computer does make it work. Sometimes (maybe always?) if I leave it plugged into the computer USB port for a few hours and then plug it back into the hub (without rebooting) it will work again.

This is not a serious problem, I am just kind of curious about what could be causing such behavior. Maybe the inverse capacitance bias modulation rectifier needs tweaking or something.
