Is it self build or from a distro? Which version? I use default Linux kernel from Ubuntu 16.04. Now It is 4.4.0-47-generic. This problem is solved by modprobe ieee802154_socket. Now my RPi 3 and PC can wpan-ping each other via two atusb. :) Thanks. > > regards > Stefan Schmidt -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
