Are there any confirmed miners like cgminer that will work or has worked with them?
It's to come with it's own on-board miner host. All you need to do is plug Avalon into a DHCP-enabled LAN, configure using a browser (presumably), and you're mining.
I believe internally it's to run cgminer or bfgminer (I forget which), and is to be all open source and friendly so you can connect your own miner host if you wish instead of using the onboard one.
