Hi,
This is constraint of Jetson Nano developer kit. The micro-B port support USB2 device mode. USB3 device mode is not supported. Please note this.

Hi,

The print may be incorrect. Please check the carrier board specification:

https://developer.nvidia.com/jetson-nano-developer-kit-carrier-board-p3449-b01-specification

In 2.1 USB Ports, J28 port is shown in table 2-1. It only has D+/D- pins and no USB3 TX/RX pins.

Looks like your topic is in wrong category, you should be using Orin Nano developer kit instead of Jetson Nano. Please refer to
https://developer.nvidia.com/downloads/assets/embedded/secure/jetson/orin_nano/docs/jetson_orin_nano_devkit_carrier_board_specification_sp.pdf

If you connect to J5, it should switch to device mode automatically. Please use type-A to type-C cable, connect type-A to the post PC, and connect type-C to J5.
