Hey guys, 


I am trying to activate an LED connected to a usb port when the mouse is active. Does anyone have any ideas? So i will have a circuit that has an LED, the circuit is connected to a usb port. As soon as the mouse is moved, I want my LED to light up.

Looks like someone beat you to the technology so if your really interested on what the circuit board would have to look like you can buy one for 15 bux and disect it.  Basically data is carried over pins 2 and 3 so you need your LED to ' light ' when voltage is detected on the MOUSE side of pins 2 and 3 on the USB plug.
