Only thing I can note is that your build doesn't pick up my two IceFurys. It works fine with the 10 Antminers, two Jalapenos and 3 proxies. Doesn't even pick up the NFYs if I specify them in the command line.
Make sure you used Zadig to install the driver for the IceFurys. It
is needed for those. I am using that exact same Windows build to run IceFurys and Antminers without issue.
Ah, OK. I just moved the IceFurys to my BBB, so no big fuss.
