Tap into your power supply instead, as the USB bus has a limited amount of 5volt power.

a 13v light, tapped into your PS's 12volt line will probably be brighter than a 5v light.......
(but I'm no expert so I shouldn't be adding my 2 cents here.

its doable, but you have to worry about whether or not you will be using other usb devices. if you hook it into a powered usb hub, you wont have to worry as much..

It's probably better to put the power supply at risk of shorting than the USB ports and the motherboard (as is my understanding).
(I'm no expert either, just reciting what I learned from others).

Is that so you wouldn't have to run a wire except for the USB from the trackball to the PC?

Exactly....that is what I wanted to accomplish.....but if it will cause problems, I can do it the way others are suggesting.......I definitely go with a high wattage bulb if I have to run the power wire....
thanks all

I was wondering the same thing to power my 5v lcd panel...
There are two pins on the IPAC that supply power and a ground...
If you are using an IPAC, try getting power from there.
