I want a simple program that will disable my USB or stop power to it. I think if I manually go and disable it or tweak a setting in device manager I can accomplish this, but I would like for me to be able to set a timer when the USB cuts off so I don't overcharge my iPod while I sleep. I saw an external device for purchase online, but I'm hoping to download some software for free. I know this would at least be possible using javascript and clicking the disable USB option in device manager, but perhaps someone has already written a script for this?
