I plugged my passthrough into the computer and it worked like a charm. Then the wonderful people here told me it was a bad idea, so I unplugged it. I plugged it into the wall-to-USB charger........and nothing. I plugged it into another wall port, and still nothing. I checked the wall-to-USB with another device and it worked. I figured I had somehow fried my pass-through so I tested it out on the computer USB port and it started working again. It doesn't make any sense. Why is it working on my computer, but it's not working on a wall adapter. What gives?
