The motherboard has a 19-pin USB3.0 specifically plugged into the chassis panel to support 3.0 USB, if your device is 2.0 then plug the motherboard 2.0 socket, plug can not be 3.0, even if you can plug it will not speed up the number of data transfer degree!
If you want to change the conversion connector, but there is no point in installing a good 2.0
You want to experience the 3.0 USB, then buy a usb3.0 front panel
