They draw 0.5A from what the EE has told me.
The command would be along the lines of.
bfgminer -S bigpic:all -o pool -u user -p pass
Also if you are using bfgminer from Luke's build you won't be able to probe for both block eruptor and blue fury as both probes will break each other. If that makes sense?
Hmm. I plan to run two separate instances of bfgminer, where one instance would only control/probe for Erupters (-S erupter:all), and the other - only BFs (-S bigpic:all). Hope this works. If not, I'd need to plan for all BlueFuries running from a separate machine.
I don't think cgminer has the same issue. One option would be use a old version of bfgminer sub 3.3.0 so it is only compatiable with the block eruptors and then use our version of bfgminer. Theoretically that should work. Luke might know a better idea or he might have some kind of fix in the works I am not sure.
