vader:

and I use that word lightly......can I just tap into the power on the interface board on the USB Happs trackball to power the led light for the translucent ball....if I remember correctly, usb supplys 5 volts so this should work......I think

paigeoliver:

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

RayB:

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.  ;D )

Bgnome:

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..

DaveMMR:

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).
