Small update: I’m pretty sure the DTB is being loaded properly now as the machine name does change between when it’s applied and when it’s not:
Without custom DTB:
Machine model: Jetson AGX Orin Developer Kit
With custom DTB:
Machine model: NVIDIA Jetson AGX Orin - AVerMedia D315
Unfortunately the application of said DTB file does not make the USB3 ports work, they remain just as inactive as they were before. Since we’ve already tested that they’re not physically broken, what could cause this behavior? Does BalenaOS need any extra ‘help’ aside from these DTB files?
I checked the USB firmware version as well and -far as I can tell- it should be the latest available version:
Firmware timestamp: 2023-02-10 03:48:10 UTC, Version: 80.05 release
Some relevant excerpts from the dmesg output:

I also came across this thread, but it doesn’t seem to have gone anywhere.
