Is anyone running a Pro Tools set up with an Mbox 2 on a unibody MBP? Those that are, can you answer me if your setup can run 100% off a USB port on the MBP? The reason behind these questions is that I have had a Tascam US-122 for a few years now. I upgraded my white MB to the unibody at the end of this past summer. Because of the green initiatives Apple is taking with their computers, the USB can no longer power the US-122. I now need to run it through a powered USB hub for extra juice. At home this is fine because I already run a powered USB hub. But on the road where I do a lot of small recordings, it defeats the purpose of having a mobile recording interface, which is why I bought the US-122 in the first place. Plus it's extra hassle. The next logical place to look is the MBox 2 by DigiDesign. Anyone with similar setups able to answer my questions? Or if you have an alternative solution, I'm also open to that. A friend suggested the Apogee Duet but that's too pricey when you're just getting the hardware.
