Possible to turn off power to a USB device?

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.

    Go to device manager and disable the webcam. It is under the universal serial bus controller section(last).

    Right click my computer > properties > device manager(left side) > universal serial bus controllers > webcam name
    Right click on it and select disable.

    When you want to reuse the webcam, use the same procedure and right click and select enable.
  2. Thank you. I should have remembered that. Could it be possible to do with the command prompt or just the right command in Run?
