Just pulled the updated version of cgminer and built it on my pi3, so I'll be ready when the time comes. Also decided to ditch minera and just have it auto-start cgminer in a screen session on boot.
Interesting - can you share how you did that? I usually go crazy trying to figure out the software setups and I'm trying a pi this time around
I have had a pi up and running with the 2pac's as well. It's a little more that what is listed on the support thread but that has most of it.
For the USB stuff
