MBox 3 Lights flashing

[pedsmd]

I was using my mbox 3 for months without any difficulty until I accidentally plugged in a 2nd mic while the phantom power was on. Within seconds the USB port was shut down on my mac with the red flag and the lights on the mbox started alternating in the circle of death. I can't plug it into any computer to make it work now. Anytime I plug it into my macbook pro it quickly causes the usb port to be disabled. I'm afraid I've ruined something internal to the device. Any thoughts on how to make this work? Should I go ahead and try an external powered usb hub at this point or have I most likely fried the mbox?
