Upon plugging or unplugging the headphone, the unitid of 11 matches the unit in `trx40_mobo_connector_map`, although two events are happening - two for plug and two for unplug. There's another event for '7', and changing the second item of `static const struct usbmix_connector_map` from 11 to 7 does not seem to affect it.
