Must there be a timeout? Is that the intention of the WPS spec? It makes
sense for WPS PBC, but not necessarily for WPS PIN. In my case the device
could very well be waiting for WPS PIN request for a long time. It has a
push-button but that button is used for WPS PBC and it doesnt seem to be
possible to run wps_pbc and wps_pin concurrently.
