Argh, 
CGMiner is now showing all AMU devices, but those above AMU 3 are randomly showing 'invalid nonce - HW error'.
They're on a powered hub, but some consumer feedback indicated that the necessary power wasn't being sent to all ports in the hub.
Any thoughts?

How many ports do your hubs have?
What is the voltage and current the power supply for the hub capable of?
How many Block Erupter USB's are you plugging into each hub?
I have 7 port hubs which have 5 powered ports with 5Volt 2Amp power supplies. I plug in 4 Erupters per hub which draws the max of 2 Amps. Which isn't really a good idea to max them out like that but it's working OK for me so far.
