I just replaced my mobo with a Gigabyte-p45-ds3l and my razer copperhead mouse will not respond. It lights up completely but does not move the cursor at all. I have tried moving it to all 8 usb ports on the front and back of the machine. My razer keyboard, and my razer barracuda headset work fine in the usb. The human interface devices can read the copperhead but always has an error that says that is has the same name as a service name. Any ideas?
