Didn't know if to post this in working, or non-working. The device sets up great, and supports monitor mode, and even WEP injection. However, I've run into several problems recently when using it in BT4pf to capture WPA handshakes. It appears to do one of several things:
1) will monitor the network, but not detect clients associated with it. (Works fine with same device in BT3)
2) capture valid handshakes on WPA/WPA2 (will capture the handshake, but will apparantly not capture enought to decrypt the correct passphrase. e.g. password is paul24you, it comes back saying password is paul24. Again, this is something that it does perfectly under BT3)
Other then that, it works great, and the external antenna connection is a lifesaver.
^^code to get it up and running in monitor mode under airodump
macchanger --mac <spoofed MAC> wlan0
ifconfig wlan0 up
airmon-ng start wlan0
