My goal is to write a MIDI music instrument with the Jetson Orin Nano and plug it into a PC to connect it to a synth using MIDI signals. the USB gadget is there, but it’s used by the L4T, presumably to allow the PC to see it when you want to connect it using the SDK manager for example. How I can …

Thank you DaneLLL, that worked for removing the l4t gadget. My problem now is that I need to add midi support in the kernel for my gadget to work.

Problems attempting to setup a USB MIDI device (not host)

Hi,
Please try to remove the service and see if your use-case works:

/opt/nvidia/l4t-usb-device-mode/nv-l4t-usb-device-mode.service
