I have an ASRock Extreme4 Z77, it seems there is a problem with one of my USB ports. At first I had my mouse connected to it and the mouse would occasionally disconnect and reconnect. I switched the mouse to another port and the mouse stopped disconnected. However, I connected my USB headset to it instead, and I noticed that the headset is now disconnecting and reconnecting back in. Came to the conclusion that it is the port that is having problems. Any ideas?
