They must advertise WPA at some point if you manage to connect with
ap_scan=2.. wpa_supplicant will try to scan for the specific SSID if
scan_ssid=1 is used in ap_scan=1 mode. If the driver supports this and
works correctly, it would include that WPA network in the scan results
and wpa_supplicant would then try to connect to it.

Is the hidden network visible in scan results when scan_ssid=1 is used?
wpa_supplicant will alternate the scans between broadcast SSID and the
SSID. I would be interested in seeing whether the scan results for the
specific SSID show the WPA/RSN IE correctly or not.
