Both.
I set up using a keyboard and mouse, then run the pi's and connect remote via VNC.
I have 9 ML2's ssplit over 3 RPIs and they exhibit similar levels of instability on v34 irrespective of USB hub, frequency or voltage settings. So hopeful for new version if i can get it running, but i get the missing bfgminer error.

Missing bfgminer is normally caused by communication problems with hubs. What hubs are you using? Have you updated your pi? Can you try 1 ML2 in one hub hooked up to the pi? Do you have a PC you can try the hub on? We are assuming you downloaded the library's needed, libjansson-dev and libcurl4-openssl-dev?
