you are right. using interface wlan0 does the right thing. thanks for
the hint.
you were asking for additional info on my situation. here is the output

    ...

the output after the newlines come from a testing notebook with windows
vista sp1.
the AP does not show up there.
is there anything i could try?

here is my config:

    interface=wlan0
    driver=nl80211
    logger_syslog=-1
    logger_syslog_level=2
    logger_stdout=-1
    logger_stdout_level=2
    dump_file=/tmp/hostapd.dump
    ctrl_interface=/var/run/hostapd
    ctrl_interface_group=0
    ssid=blackbit
    country_code=AT
    hw_mode=g
    beacon_int=100
    dtim_period=2
    max_num_sta=255
    rts_threshold=2347
    fragm_threshold=2346
    macaddr_acl=0
    auth_algs=3
    ignore_broadcast_ssid=0
    eapol_key_index_workaround=0
    eap_server=0
    wpa=1
    wpa_passphrase=abcdefgh
    wpa_key_mgmt=WPA-PSK
    wpa_pairwise=TKIP CCMP

please tell me if additional infos could be of use.
