Razer wolverine ultimate help

I bought a wolverine ultimate off of ebay (so no serial number) and it was working amazing for a couple months, then all the sudden I wake up and it is making a ringing noise, turned the xbox on by itself, and was going crazy with inputs. I naturally unplugged it, but once i plugged it back in it no longer works. I got the ringing to stop by brushing out the usb port, and once i plug it in the controller vibrates (as it normally does) and the lights come on (as it normally does) but the controller still doesnt read ANY buttons I press. I tested everything else vigorously, and it is definitely the controller. Any suggestions? has anyone else ran into this problem? Thanks.
