Reply to Anyway of modifying the Audio 10?

I've been using TSP2 for the past few months and it's great (I escaped the planet of SSL) but one thing that really annoys me is the need for a power supply when using the Audio 10 soundcard! Is there no way to modify this?? I know the Macbook Pro 2011 models have higher power output usb ports..perhaps some sort of hardware hack could allow the port to power it or piggy back off the thunderbolt/firewire ?

I've also looked at getting an Audio 8 off ebay but i'm concerned that no new updates will be released for it so newer versions of traktor down the line may not work as well?? Audio 6 is another option, I use three decks so I'm assuming I could use the main ins and outs for the third deck?? (please correct me if I am wrong) anyone else have any other suggestions??
