I am using a Dell XPS 8930 Desktop
This desktop comes with a several USB 3.1 gen 1 ports (USB 3.0 or SuperSpeed) and one USB 3.1 Gen 2 ports (USB 3.1 or SuperSpeedPlus).
There is one USB 3.1 port on Back Panel. See picture below.
I noticed that this port still performs at SuperSpeed only.
I am suspecting that this is because the USB Root Hub driver that runs on top of the underlying host controller is still USB 3.0, and not USB 3.1.
Here is the view from USBTreeView software. No devices were connected to any of the USB ports when I took this screenshot.
Also, Device Manager shows two separate "USB Root Hub" entries. Both of these entries show the driver is a Microsoft driver (dated 5/9/20, Version 10.0.19041.264
I have two questions.
(1) There is only one USB 3.1 port on this computer. Why is there a "USB Root Hub" running and showing four ports? Whenever I plug in anything in that 3.1 port, it shows up under "Port1" of the USB 3.1 controller.
(2) How do I enable 3.1 performance on the USB Root Hub driver? I have searched for "USB Root Hub 3.1 driver" but cannot find anything. The manufacturers (Intel and ASMedia and Dell) provide only the controller driver (which I obviously have), but not the USB Root Hub Driver.
Thank you in advance,
