Using device_attach() works without header change. But bus_probe_device() is needed for check the autoprobe status. Example: User disables Autoprobing The default interace authorization is off The user enables an interface Without bus_probe_device() and with device_attach() alone the driver will get probed. With bus_probe_device() this is not done. The user can manually do with probe_device from sysfs. > thanks, > > greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
