It requires only a free usb port. That's all. ( for intuos, bamboo series, cintiq ones need extra power of course )
With some models you will receive a extra wireless mouse ( no batteries needed ).

If you take the trick, you won't use a mouse anymore. ( you will find it too "slow"  ). It's faster to point and click with a stylus in your hand.
