I have an external unit with the slim slot drive in it...Originally Posted by windalo
It gets its power over the usb , but mine came with a cable that connects to the PS/2 port of mouse or keyboard to supply power and the connector still allows you to plug in the mouse or keyboard.
The cable is only a couple feet long, but being a power cable, it should be able to be extended without too much problem.. I know if it was getting power from the usb alone, there would be a limit on the length...
hope that helps
