Device Path Name for Micro USB Port?

[user51473]

Hi there!

I’m trying to figure out the /dev path name for the micro-USB port on the Jetson Nano 2GB Developer Kit (945-13541-0000-000)

I know to use the UART on the pinout to use /dev/ttyTHS1, but I cannot seem to figure out how to access the micro-usb port.

Any help would be awesome!

The dmesg will tell the mapping of each UART for each tty console.

Please check which UART<-> tty* is what you want first.

Thank you!

On my device it is /dev/ttyGS0

That micro usb port is a special one with some drivers get involved. You can check 3
