Hi Wayne,
With TX1 SOM on my custom board USB devices are detecting.
But with TX2 SOM on the same custom board there is no downstream device detected and getting below logs for usb:

I followed this thread Third USB on custom board not working with JetPack 4.2
- and added hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-quill-power-tree-p3489-1000-a00-00.dtsi

================================================================
So can you please suggest are the above changes fine or still dtsi needs some update to enable USB 2.0 in custom board with TX2 SOM with R32.4.3 sdk.
Any help will be appreciated.
