Yes.

That looks fine as far as initialization is concerned, but it does not
show any authentication/association attempts from a station.

And interrupts are being delivered. Good.

And this is OK, too.

Hmm.. That "<INTERNAL STAT" looks odd.. This position is usually
reserved for station firmware identifier and I have never seen such
identifier.. Maybe card manufacturer has used some special station
firmware image(?) Everything else in hostap_diag output looked OK.

Yes, everything seems to be OK as far as card initialization and
configuration is concerned. Unfortunately, I cannot see anything that
would indicate what is causing the problems. You could also enable all
RX/TX packets dumps in the driver with 'iwpriv wlan0 dump 7' (or
'utils/prism2_param wlan0 dump 7' if you are not using wireless tools
version 25 or newer).

Next step would be to setup a third host as a wireless sniffer and make
a dump of all frames sends by the station and the AP.. This should be
able to confirm whether the AP is sending beacons and is responding to
station's probe request.

Easiest way is to download a snapshot of the CVS tree from
http://hostap.epitest.fi/. Direct link for this is
http://hostap.epitest.fi/cgi-bin/viewcvs.cgi/hostap/hostap.tar.gz?tarball=1
