I'm having an issue with my front USB panel (2 3.0 and 2 2.0). I first noticed when I went to plug in an Xbox controller for a game I was playing, and it didn't pick up the connection. However, it did begin to charge. I then plugged in one of my USB storage drives to see if it would work (wondering if the cable was the problem) and it didn't pick up either. The only thing I can guess that caused the problem is a USB fan that I had plugged in the day before, which had gave me an error message saying there wasn't enough power (the message popped up about 10 times before it went away). So now I'm lost in what to do to fix it.
