I have the gigabyte ga-z77x-ud5h motherboard. I came with the WiFi and Bluetooth feature. The WiFi works fine and I just figured out why the Bluetooth isn't working. It needs to plugged in via usb port. Only problem is, there seems to be only two usb 2.0 ports on the motherboard which are being used by the case. There is a f-1394 port which looks like the usb port, but I read your not suppose to use that for usb plugs. So am I out of luck of using the Bluetooth without unplugging my other usb ports?
