My Guitar was working fine until I tried using it on xbox 360

I was using my guitar that is for the xbox 360 and was using it for my pc. Everything was fine until i tried using it for my xbox 360 and the guitar didn't signal that it was on. I tried pressing any of the buttons but i wasn't getting a response. If i could get some help i would very much appreciate it
