HS13 and HS14 are USB 2.0 ports. The rest of the ports on the machine and USB3.0. The motherboard is a Gigabyte 170x-ultragaming. I have connected 2 USB 3 ports to the montherboard front USB 3.0 header from the case. The case USB 3.0 ports are HS01 and HS02 with HS03, HS04, HS05 and HS06 being the rear USB 3.0 ports.
You will see in the ioreg that HS13 accepts the USB3.0 device but none of the other ports accept it. HS14 accepts it too but I didn't connect it in this example.
