Hi,
I use the Preconfigured miner options for

Minera 0.6.1
BFGminer 5.x (Official)

BFGminer Zeus miner+ Gridseed mixed

here the commandline i use:
--scrypt -S zus:all --set zus:chips=128 --set zus:clock=200 -S gridseed:all --set-device gridseed:clock=800

I use lower Clock then normal, because I changed the fan to low noise fans ;-)

For the setup, i dont know if this makes the "magic" that it runs ;-)
I first added the Zeusminer, after this was running fie i added the Gridseed.
My setup:

Raspberry Pi with minera 0.6.1
the Zeusminer Thunder is connected directly ti the PI
The two Gridseed Blade (4 boards) are connected to an powered D-Link Hub and the hub is connected to the PI.

hope that helps

Best
Stonie
