No new port detected when plug in USB2.0 device

[ishigetw]

My USB3.0 PCIe card was ORICO PME-4U. It was okay when plug in USB3.0 device and port show up, but when plug in USB2.0 device will not detect new port. If I create USBmap.kext then I will not able to use UBS2.0 device. Any thoughts?
I know this card should support by Apple driver, but I have problem when I connect may Canon camera, it will fail because of "connection lost". After I use USBmap will solve the problem but lost USB2.0 capability of these USB3.0 port. That's why I hope I can get rid of this problem.

I have the same issue with USB2 not detecting. I'm on Big Sur on a Coffee Lake board.
