Keyboard, Trackpad, and USB unresponsive on ANSI PBP

Good news, I got the USB ports working. However, I have no idea how I did it. I was testing the voltages on some other components I identified and forgot to power down the PBP board before I left to run some errands. When I came back, the light of the USB hub I had been using as a test device was on.
Naturally, I'm thrilled that my device is working again. I am a little bit frustrated though that I have no idea what the issue was. I hadn't done anything more than touch a bunch of components with my multimeter.
So, if anyone stumbles across this thread in the future because they're having the same problem. I'm sorry to say that I can't really help diagnose the problem, but perhaps just try leaving it powered from mains for a few hours?
