We developed a special version cgminer for dualminer. The customization is mainly because cgminer on github doesn't support dual mine mode. The latest version of cgminer even removed scrypt support, :-(. Also we are keeping a eye on bfgminer. We may release a bfgminer for dualminer. Currently only a customized cgminer is developed. As long as we start mass shipping, we will release cgminer that works on Linux. At that time, Beaglebone or PI can be used to control/manage dualminer usb.
