I have been testing with a BBB and have been getting good results, surprisingly as a BBB often has USB issues with devices. I also tried using a Odroid C2 which doesn't even see any devices so is totally useless. My next test is al old Odroid X2, which has been used as a controller for all of sidehack's and many other different miners. The only miner so far it hasn't worked with is the futurbit's.
BBB: Debian, Rosewill 10 port USB 2.0 hub
4x 606 390mv 180watt 1.9 / 1.92th
4x 606 430mv 320watt 3.16th
that would be interesting to follow...I've been eyeballing the Odroid XU4 since it's got some hefty horsepower to hopefully allow me to turn the miner all the way up if I so desire. I'm just not too fond of having to buy a separate screen and create a housing and/or mount for it if I go that route.
