zyd vs ural for Belkin F5D7050 rev 2

I have a Belkin F5D7050 USB 2.0 wireless adapter (rev 2) that I'm trying to
configure.
I followed the setup instructions in the handbook (30.3) and end up with
wlan0 with no ssid and no authentication. I have an
/etc/wpa_supplicant.conf file per the handbook (network={ssid=...), and
/etc/rc.conf with wlans_zyd0="wlan0", ifconfig_wlan0="WPA SYNCDHCP".

When I read through the dmesg output, it appears wpa_supplicant is loading
zyd (which does not support rev 2). I can use zyd to scan the local
networks (ifconfig wlan0 scan), but it won't connect, no ssid, no carrier.

Would using the ural driver help? How do I override wpa_supplicant to
choose ural over zyd? (it looks like the wpa_supplicant "driver" right now
is bsd)

I'm running CURRENT rev 292767.

Thank you!
