Bfgminer works fine with the S9. Sounds like you have network or electrical issues. What kind of power are you feeding the S9? What's your network setup?
Are you using BFGMiner? sorry - I meant to ask, how did you get it to work? Did you build the executable? I'm stuck...
I posted to its forum and I was told that S9's are not supported...
Thanks
My questions as well.
The s9's are stand-alone miners with their own controllers and BMminer miner software (Bitmains ripped off version of cgminer).
So,
a. Why on earth would you want to try and re-invent the wheel by using a different controller/software?
b. How did you write a driver to interface between the s9 hash boards and BFGminer?
