yeah that worked, running with Block Erruptor USB now!
- compiled cgminer 3.1.1, and copied the executable to /opt/minepeon/bin
- added -S /dev/ttyUSB0 -S /dev/ttyUSB1 etc. to /usr/lib/systemd/system/cgminer.service
Can you note down exactly what you did here? I still don't have any Eruptor's to play with but I would like to see exactly what you did (git clone, configure, service changes and everything).
