All that is in tree is ./Documentation/usb/functionfs.txt which I can not get the information I need from. I happened to find https://events.static.linuxfound.org/sites/events/files/slides/LinuxConNA-Make-your-own-USB-gadget-Andrzej.Pietrasiewicz.pdf, but the commands within did not work and I do not know how to troubleshoot. I am trying to work on getting libusbg or libusbgx on my device. Is that the recommended method? When using gadget drivers, how is the device-capable port specified if there is more than one?
