Well that's unfortunate.
When I was making mods to the AppleUsbAudioDriver, all I had to do was turn the device off and run the kextunload command.
Clearly, something is latching onto ARD and not letting go.

Like all drivers, the Reflector driver can't be unloaded while it still has open user-clients attached to it. Typically, you need to quit all the apps that might be using audio to unload a driver that is being used actively. Note that processes like LoginWindow and SystemUIServer always have the HAL initialized and will open a connection to a freshly installed driver as soon as it shows up on the system.
Because of this, typically the easiest way to get a new build of a driver running is to just reboot after installing a new build.
