As Alan Stern explains[1], this is the normal behavior: "It is a temporary measure, used only when the file system is set up initially. The real bind routine is gadgetfs_bind(), which gets called when userspace configures the gadget. In short, this is how it is intended to work. It isn't a bug." [1] http://marc.info/?l=linux-usb&m=138029668707075&w=2 So in order to prevent the error message, do not report EISNAM as an error.
