are only prism2 chipsets supported?

[Christian]

Hi List,

 i have a noname WLAN Card and like to use hostapd. But i get the
 following error:

 ------------
router root # hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Operation not supported
Could not enable hostapd mode for interface ra0
ioctl[SIOCGIFFLAGS]: No such device
ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Operation not supported
router root # 
--------------

 is that right, that only prism2 chipsets are supported? I have
 hostapd 0.1.0 installed?


Thx
Chris
