someone has a working cgminer with extranonce subscription for the antminer S4 ?
The one on the nicehash site doesn't seem to work....

However, I am getting over 1900 GH/s accepted using default code. I set the following in /etc/init.d/cgminer.sh based on the site recommendation. Edit the line with PARAM= and add "--queue 0 --scan-time 1 --expiry 1". This is not persistent past a reboot, so have to edit again if reboot occurs.
