After reading several posts on the forum. I have understood that reconfiguration is required in custom carriers to enable it.

Can anyone share the procedure for

1. Enable USB 2.0 ports
2. Configure PCIe and USB3.0

I am using JetPack3.0 and L4T 28.1.

Hi vishwanath.nm,

You need to know the USB configuration for lane mapping, then make the suitable change of device tree.  
Please refer to the [Jetson TX2 Platform Adaptation and Bring-Up Guide](https://developer.nvidia.com/embedded/dlc/l4t-driver-package-tx2-adaptation-guide).

Thanks

hi kaycc

Jetson TX2 Platform Adaptation and Bring-Up Guideis for USB3.0/PCIe configuration selection.

What about the USB 2.0 ports not working?

I tried the solution according to [url][https://elinux.org/Jetson/TX2\_USB[/url]](https://elinux.org/Jetson/TX2_USB%5B/url%5D) but this did not help.

I am not suspecting the hardware as port 1 is working but port 0 and 2 are not.
