I am pretty Minera image should work; as long as it has the latest CGMiner - the newest CGMiner has Prisma support included - no need for the special AM fork.
I am using mine with BE Controller thru BFGMiner proxy & using Awesome Miner for monitoring. Getting graphs from MRR...
Waiting on usb-uart so I can get it going with RPi w/ Minera
Is there any type of Rasp Pi image available with a nice web interface for these? Or just use wheezy and cgminer?
