are you running it for a laptop or a desktop please e-mail me and i will try and trouble shoot it for you but my best guess is that USB port isnt getting enough power from the powersupply and that you need to get a new one or that your usb isnt compleatly plugged into the motherboard. but if it is a laptop your keyboard may just be to elite for the computer and finnally you may have to much plugged in just keep what you need plugged in if none of these work than e-mail me and i will continue the trouble shooting.
