I am new to the Avalon product line and I am having problems getting the Controller to communicate to the miners and start mining.  The attached pictures show my setup with 2 Avalon 721 miners and 1 AvalonMiner Controller.  I can communicate with the Controller and have configured it to work on my network, but it doesn't show any miners attached.  I have tried the following to troubleshoot:

 Switched to all 4 of the usb ports of the controller
 Justed hooked 1 miner up
 Switched miners
 Bought a new  power supply for the controller
 new usb-to-micro cable for controller to AUC3
 switched auc3's

The controller is still unable to communicate with the miners.  Do I have to flash the sd card in the controller or should it come ready to go out of the box?  I have been communicating with Canaan but they have gone silent.  I am sure I am missing something stupid, so any suggestions would help.










Thanks!
