Proxmox 7.4 USB speed issue

When I use my USB NIC, all USB ports are at USB 2.0 (Includes usb3 interface)

The wire has been checked and there is no problem.

Because of this strange problem, my windows 11 virtual machine is not performing well (such as USB sound card audio stuttering).

I have switched from proxmox ve to windows 11 for this reason.
