ok everybody is right...they require more power than standard USB provides. Griffin invented iFire. Since Firewire provides the nescessary amount of power, the adapter plugs into your computers firewire port and the audio in port. Then you plug the USB apple speakers into the iFire. Funny thing is you can also power it with the old iPods too! Then you have some working Apple Pro Speakers!
