Ok, my xbox is about a year and a half old and about 3 months ago, my controler just up and died, so i couldnt figure out what happened, and blaimed my bro, then the other night i was with my friends and a brand new controller (opened the day before) dies, and i have come to the conclusion that my #3 port is frying my controlers, has this happened to anyone else and is there anything i can do about it?
