JP3.3 R28.2.1 USB devices not recognised on PCie card

Hi,

I have a PCIe 3.0 USB hub connected to my TX2. It worked fine with JP4.2. Unfortunately I’ve had to go back to JP 3.3 to try to resolve some other issues with rtabmap_ros.

I now find that I can’t access the USB devices connected to the hub. I saw a few previous posts related to the issue but they seemed to relate to R24.2

(L4T R24.2 PCIe IOMMU not working when switches (bridges) are present - Jetson TX1 - NVIDIA Developer Forums)

I thought this issue had been patched for R28. Any thoughts?

Hi,
http://www.galileo.com.tw/025-06-01-04.html
We have the device and it works fine on both JP4.2 and JP3.3. Do you have other cards to give it a try? Cards with Renesas chips.

Hi DaneLLL,

Thanks for letting me know that yours does work. Same VIA chip?

I’ll try to find one nearby with the Renesas chip.

Any other ideas to get this working from anyone are very welcome still!

Ta,
Ben
