I'd like to add some information here about this issue, which in one of my computers happens when using a Software Defined Radio (SDR) device on some of the motherboard USB ports:
* The device works OK when using the back panel USB 3.2 Gen 1 ports
* It doesn't work OK when using the back panel USB 3.2 Gen 2 ports, or when using the front headers (either USB 3.2 Gen 1 or USB 2.0)
When I finish using the device, the following message gets logged. I have to disconnect it and plug it in again in order to use it:
xhci_hcd 0000:02:00.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state.
This motherboard is an ASUS Prime B550M.
Kernel 5.4.0-45-generic (from Ubuntu 20.04).
I've tried booting with "intel_iommu=off" or "iommu=off" just for testing, but the result is the same.
