Have you made sure no other stuff are connected to your computer like an external hard drive, blue tooth recievers, any other stuff that uses usb ports just in case that it's the BUS speed of your motherboard that is lacking?

There is also the very serious possibility of your power source being too low of a wattage to support a secondary monitor which is what the headset is basically. If your power source is 3kWatts and up it should be ok though usually.
