Hello! I try to turn on usb gadget mode on my OPi. For example g_ethernet, or g_midi. Read many posts, but still don't understand what I should do. Is it possible to turn on gadget mode without compiling my own armbian? Also, I had found on this forum info that legacy roms already have OTG support from the box. Is it true? May be somebody knows tutorials of how to turn on usb gadget mode?
