Does this only work on RPi4? It seems to me that this should also be working on the other RPi's. Do you have such HW to test?
It should work on any RPi with USB device controller available on the micro-usb/c-usb connector. AFAIK, besides RPi4, only some RPi0 has USB device mode available. Other RPi's have USB hub connected to DWC2 controller, so switching DWC2 to device mode is not enough to make it working.
However I have access only to RPi3 and RPi4.
