You might try this: Unplug your Hopper from power. Next unplug the EHD. Now plug the Hopper back in and let it reboot. After reboot plug the EHD back in. Hopefully you see the media device plugged in slate pop up.
Not sure if it was this update, but when it was storming here last night, when i hit the guide button, at the bottom in blue it said " sat signal lost, click select to see streaming channels" . That is the first time i have sen that. Also when in the guide it showed if my ota channel was receiving a signal or not.
