Hi there,
As far as I know, Vmware workstations have a similar problem. If the host PC supports USB 3.0 and you have a client that only supports USB 2.0 like Windows XP, the only way to solve this problem is to use a USB 2.0 hub in between.
I'm having the same problem in Proxmox V8.1.10 (xhci_hcd 0000:01:1b.0: ERROR transfer event TRB DMA ptr not part of current TD ep_index 8 comp_code 13)
But my client is Debian Bookwork, which should support USB 3.0 with a USB 3.0 hub in between.
But after connecting the USB 2.0 hub, the messages disappear.
Unfortunately, I don't know of any software switch in Proxmox that does a downscaling to USB 2.0.
