Razer Atrox (360) No Power - Bad PCB or USB?

I've had my Atrox for a little over a year and have less than 10-hours of game time on it. I went to fire it up last night, and no power. The lights are out and neither my 360 or PC recognize it. I suspect it may be a bad USB cable but it could also be the PCB.

As I wait to hear back from Razer on whether I could purchase a new USB cable, are there any suggestions or tests that I can do tell what the problem may be?

Thanks.
