wpa supplicant fails to start

[Martin Smith]

>From dmesg:
May 15 13:38:32 lp2 kernel: ath0: <Atheros 2417> mem 0x88000000-0x8800ffff
irq 11 at device 0.0 on cardbus0
May 15 13:38:32 lp2 kernel: ath0: [ITHREAD]
May 15 13:38:32 lp2 kernel: ath0: AR2417 mac 15.0 RF5424 phy 7.0

My wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
  ssid="myssid"
  scan_ssid=1
  key_mgmt=WPA-PSK
  psk="my wpa secret"
}

I have put this together using both the handbook and the
wpa_supplicant.conf man page, do I need to add anything else?

I get this error:
lp2# wpa_supplicant -i ath0 -c /etc/wpa_supplicant.conf
ioctl[SIOCG80211, op 98, len 32]: Invalid argument
Failed to initialize driver interface
ELOOP: remaining socket: sock=4 eloop_data=0x28406140 user_data=0x2840d040
handler=0x8069f50

I obviously have something wrong, can anyone point me in the right direction.

System is current as of yesterday rebuilt.
Card is TP-Link TL-WN310G
Machine is a Thinkpad X23

lp2# ifconfig -a

Thanks for any pointers
