Hi ,

We have a NVIDIA custom board, which is similar to Jetson TK1 and we are facing some issues in enabling USB3.0 port . From the debug logs i could see that Tegra\_xusb\_firmware is loaded but the interrupt response is not seen. Below are the USB details of our custom board .

1. USB3 port 0 and USB2 port port 0 are used for USB3.0
2. Modified the padctrl configurations to select the respective ports (TRM section 19.13.12.6)
3. Modified usb\_port\_owner\_info to ‘1’ which selects USB3 port 0 and USB2 port 0 for xhci controller.

This is all the info and modifications , i could get from the TRM. Is there anything i am missing ? Has anyone tried enabling other ports as USB3.0. Any help would be really appreciated.  
Attaching logs for reference.

Regards,  
Sai
