I have just bought a smart little webcam with night vision, the picture is very good, even in the dark, one problem however is that the camera has 6 little super bright LED's that come on automatically when needed, trouble is that they will be on at night when driving and white lights on the back of a car going forwards are highly illegal.

If I put a switch on the lead so it comes on automatically then the PC will have to re-detect it and install drivers each time.

Anyone know of a way to turn USB devices on and off through software without the drivers having to re-load all the time?
