I am trying to read the Mavlink messages from a CubeOrange on an NVIDIA Jetson running ubuntu.
Linux jetson-charlie 5.10.104-tegra #1 SMP PREEMPT Sun Mar 19 07:55:28 PDT 2023 aarch64 aarch64 aarch64 GNU/Linux
The Jetson can see the CubeOrange as a USB device and the Cube boots up when I plug in the USB to the Jetson.

But there is no data coming across - when I run screen, it is just blank, and my Go application for reading MavLink messages never gets an Event.
When I try on my MacBook with the CubeOrange plugged in, it works fine. I can see raw data coming across in screen, and my Mavlink reader gets the messages.
I originally set the CubeOrange up using the Mission Planner on a Windows 11 machine.
One thing I’ve noticed is that on ubuntu the USB port is using an ACM driver (/dev/ttyACM0), while on the Mac its /dev/tty.usbmodem.
Is it a driver problem? Could the Jetson not be providing enough power? Anything else them I’m missing?
