Is it possible to turn off USB power when the computer is shut down. The reason i ask is i have a webcam with automatic lights powered by the USB for use in the dark however these lights remain on (and are quiet bright) when the system is shut down

Hmm, that's going to have to be a bios setting. I highly doubt it's something that software can address.

If it's not in your bios, sounds like you're screwed.

thats what i was affaid of , Its not in bios on this board,

Oh well will have to rig a switch to the mains to stop the power fom there

Thanks anyway

It's certainly odd that your USB devices remain powered on when the system is off. o_O What motherboard do you have? Also, there might be a jumper on the board you can fiddle with.

I had a similar problem, though; I use a joystick which has a really annoying bright light on it, and I leave the computer on at night to play music and serve as an alarm clock. I can't unplug the joystick because I use it as a remote to control the music. Solution? Put electrical tape over the light. I poked a small hole in it, so I could see if the light was on if I looked close, but from a distance it's barely noticable.
