Belkin F5D7050 v4 USB not working

Hi.
I need some help. I can't tell whether or not I have my Belkin F5D7050 setup properly. I saw the two tutorial steps posted here: http://www.aircrack-ng.org/doku.php?id=zd1211rw and I followed the directions from the first tutorial here: http://forum.aircrack-ng.org/index.php?topic=5334.0.

Note: For that first tutorial, I only stuck with the first post. I saw that other person's reply about other patches and didn't use them.

System specs
===========
Ubuntu 9.10 Karmic Koala
Aircrack 1:1.0-1 from synaptic package mgr
Belkin F5D7050 v4 card
Network-Manager installed, not wicd

I tried some test commands from the 'root' level. The first is "aireplay-ng -9 mon0" which produced this result:
=========================================================
17:16:28 Trying broadcast probe requests...
17:16:28 Injection is working!
17:16:30 Found 1 AP

17:16:30 Trying directed probe requests...
17:16:30 00:1F:33:24:03:8E - channel: 1 - 'Jaxx'
17:16:30 Ping (min/avg/max): 2.973ms/6.041ms/30.501ms Power: -73.17
17:16:30 29/30: 96%
=========================================================

Then, I tried the command specified from the aircrack website, "aireplay-ng --test wlan0" which produces this result:
=========================================================
ioctl(SIOCSIWMODE) failed: Device or resource busy

ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make
sure RFMON is enabled: run 'airmon-ng start wlan0 <#>'
Sysfs injection support was not found either.
=========================================================

I have no idea if my card was successfully patched. I can only pick up one AP at a time. I installed the wicd manager, but it stopped showing the wireless AP's after I patched the zydas driver, so I reverted to the gnome network-manager. If the wlan0 command doesn't work and mon0 does, did I set this up right?
