Hello all, I feel like an idiot. I just recieved my second USB passthrough from Jason today (last one arrived last week) and I thought my first was just broken but I don't think so anymore. I think I am dumb. Soooo does the battery charge in the box? and then when that is fully charged it should work right? I have had them plugged into my MacBook Pro and they are 2.0 ports for about 5 hours now? I think, and I have one plugged into a wall charger and neither seem to be working so what am I doing wrong? I don't think it's the product. I think its me...
