求助，ARM Linux移植无线网卡的连不上自己的无线网络啊

ARM的版本是2.6.28.7
开发板是S3C2440
移植了wpa_supplicant和wireless_tool
执行wpa_supplicant -irausb0 -c /etc/wpa_supplicant.conf来连接的时候出现以下错误
ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Operation not supported
ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Operation not supported

这是什么情况，求帮助啊，已经弄了好多天了，各位大神求帮忙
这是wpa_supplicant.conf的配置
# WPA-PSK/TKIP
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="linux"
key_mgmt=WPA-PSK WPA-EAP
proto=WPA
pairwise=TKIP CCMP
group=TKIP CCMP
#psk="。。。"
psk=一串已加密的东西
}
是不是我的wpa_supplicant移植错了，还是驱动的问题啊，感觉驱动没问题，是wpa_supplicant的问题，但是找不到原因，各位大神求助了
