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,
