ATV2 doesn't show up in available device list


i cant install ATVFlash (Black) my ATV2 won’t show up in the device list of the installer app. My other 2 ATVs are shown. The ATV2 which isnt recognized is connected to the internet and is accessible through ssh.


I created a new user on my macbook and executed the setup once again. The ATV2 shown up and the installation finished succesful.
