USB-C ports doesnt send data and unstable

Hello,

We are trying to use the USB-c for data on my Jetson Thor AGX, but gets some problems. Some times I can get STM32 to show up, but not always through lsusb. I have tried both the USB-C.

Now I need to use CANdle through the usb-c, but gets no response. It works if I plug it to the other usb, but I need to use the USB-C. Any advice would be appriciated!

I use ubuntu 24.04

First doc discusses state and uses of the 3 dev kit usb-c ports.

On second doc, scroll down to USB Structure for discussion and instruction on how to modify the one useable usb-c port. Second is power. Third is debug uart.
