A "usb0" interface that has never been connected to a host has an unknown operstate, and therefore the IFF_RUNNING flag is (incorrectly) asserted when queried by ifconfig, ifplugd, etc. This is a result of calling netif_carrier_off() too early in the probe function; it should be called after register_netdev(). Similar problems have been fixed in many other drivers, e.g.:e826eafa6(bonding: Call netif_carrier_off after register_netdevice)0d672e9f8(drivers/net: Call netif_carrier_off at the end of the probe)6a3c869a6(cxgb4: fix reported state of interfaces without link) Fix is to move netif_carrier_off() to the end of the function.
