Question Super Speed USB warning notification that is false

I am getting an unusual false message about USB 3.0 ports. My motherboard has several USB 3.0 and 3.1 ports. It also has a USB type C port. I also have a PCIe 4x Startech 4 port USB 3.0 card. On the card each port has a dedicated bus.

When I plug in any USB 3.0 device into my motherboard ports, I receive a notification in Windows, "This device can perform faster if you connect it to a Super Speed USB 3.0 port." I am confused. When I plug in the same device to the dedicated startech card, I do not receive the error message.

I have tried using multiple different 3.0 devices including a flash drive, 2 HMD VR headsets, and a 4k camera.
I have tried changing bios settings. XHCI handoff. I have enabled/disabled. No noticeable difference. Tried enabling/disabling USB Legacy mode. Same, no difference.

My understanding is that USB 3.0 does not have a driver. I have downloaded all drivers from the manufacturer website Gigabyte.

I downloaded the application USB Device tree viewer. When I plug in the Logitech Brio I receive the warning, but using device tree viewer it shows the device is connected via USB 3.0. I can also chose 1920x1080 at 60fps, which is only available at 3.0 speed. When I plug the same device into a USB 2.0 slot, 1080p is only 30fps and the device tree viewer shows 2.0 speed.

So, I can verify that the device runs at 3.0 speed, but windows throws this warning every time I plug in any USB 3.0 device or restart the computer. What gives? I don't have a lot of devices plugged into USB. I get the message with only 1 device plugged in. I can't rely solely on the startech ports because some devices do not work with the controller chip.
