usb root hub port

Where do I find this port to plug it in?

On the motherboard. What exactly is the issue and what are you trying to do? USB root hub is a part of the motherboard core components, and the only thing that could be "plugged" in, would be the USB 2.0 or 3.0 header cables coming from the front panel.
