Compile and load 3 modules in this order
```
make -C /usr/src/sys/modules/athnfw/ar9271fw load
make -C /usr/src/sys/modules/athn_usb unload
make -C /usr/src/sys/modules/athn unload
```
You should see debugging messages and the `ieee80211_announce` message.
Turn the device on with `ifconfig wlan0 up` but it will lock up the terminal.
Currently, unloading the module *will* cause your system to lock up. I do not know why yet.
