Years ago, I was having trouble using my xbox 360 controllers with the usb charger attached. They worked fine at first, but after a while they would stop working. I borrowed a friends cord and it worked for a few weeks and eventually quit working. I purchased a brand new cord and it stopped working. Today I randomly decided to try them out again and with them plugged in the xbox wouldnt turn on. What is going on? It seems as if my xbox is destroying these cords?
