Nice `dm tree` command, never used it before. Even when I unbind usb_ether I still get the same error: => unbind /ocp/usb@47400000/usb@47401000 => fastboot usb 0 couldn't find an available UDC g_dnl_register: failed!, error: -19 exit not allowed from main input shell. Is there a specific gadget driver which I should bind again manually? Thanks, Miquèl
