Reference usb 3.0 expansion board

At this time we are using a Jetson Orin developer kit.

Do you recommend an extension board to use 4x USB 3.0 via pci-express?

We have tried a PEXUSB314A2V2 (board) due to its bandwidth (20 GB/s in total divided by 4 ports). This is required because many expansion boards just split the bandwidth between the ports and we need the 4.8 Gbit/s per usb port.

The problem is that using this card we have an error on DMA :

Linux pc190 5.19.0-42-generic #43~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Apr 21 16:51:08 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
xhci_hcd 0005:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 1

Thanks in advance,

Sorry for the late response.

We don’t have the experiecne with that USB expansion board, not sure if the DMA issue is related wit hour BSP or not, also not sure if any specifi driver required, may other developers help to provide suggestions.
