I use a webcam occasionally and its a real resource hog. Plus you never know if a hacker has somehow controlled it, even briefly. There are other devices I'd like to be able to switch in and out without plugging in/out. I'd like to be able to cut the USB power to these specific devices somehow. Anybody know if this is possible? Can you turn off a USB port, even through the bios upon restarting? Presently using an Asus P5Q but that will be gone soon.
