Hi,
Do you use a custom board or default board.? There is only one Type-A port on default board, it looks to be a custom board. Would like to confirm this.

And please share the release version( $ head -1 /etc/nv_tegra_release ).

Hi,
So you connect a USB device to type-A port on TX2 default board?
