Whats interesting is you say the AUC has a green light. This green light denotes connectivity yet when you look at your status page, the AUC itself isnt even registering.
Before you mess with the miner, try to get the AUC dongle read by the controller. Thats the first step before even messing with the Avalon unit itself.
The red circle below is where the AUC's should show up.
