Trying to configure wpa_supplicant with ipw2200

[Jeremy Fix]

Hi all !

I'm trying unsuccessfully to configure on linux wpa_supplicant to access to 
my AP.

The connection works if i configure my AP with WEP .
The connection works on a Windows computer with WPA .. but not on linux.

My distribution is Mandriva 2006, i installed wpa_supplicant v0.4-4 .

I give you outpuf of some commands, hope it could help :

[root] iwlist eth2 scan
   Adress : 00:07:CB:56:4E:C7
   ESSID : "Misou"
   Protocol : IEEE 802.11bg
   Mode : Master
   Channel : 11
   Encryption Key : on
   Bit rate : 54 Mb/s
   Extra : Rates (Mb/s) : 1 2 5.5 6 9 11 12 18 24 36 48 54
   Quality : 88/100 Signal level = -41dBm
   (Unknown Wireless Token 0x8C05)
   (Unknown Wireless Token 0x8C05)
   Extra : Last Beacon : 999ms ago

My wpa_supplicant.conf :

ctrl_interface= /var/run/wpa_supplicant
ctrl_interface_group = 0
eapol_version = 1
ap_scan = 1
fast_reauth = 1
pkcs11_engine_path=/usr/lib/opensc/engine_pkcs11.so
pkcs11_module_path=/usr/lib/pkcs11/opensc-pkcs11.so
network {
   ssid="Misou"
   psk="xxxxxxx"   <--- the psk defined in my AP config
   scan_ssid = 1
   proto=WPA
   key_mgmt=WPA-PSK
}

And i'm starting wpa_supplicant with :
wpa_supplicant -i eth2 -D ipw -c /etc/wpa_supplicant.conf -dd

>From the several lines of the output , i can see these following states (if 
you need the whole output, i could give it to you):

  State: DISCONNECTED->SCANNING

  State: ASSOCIATING -> DISCONNECTED

And all along the output, i can see several "ioctl[IPW_IOCTL_WPA_SUPPLICANT] 
: Operation not supported"

Thanks a lot for your help.
