Re: GekkoScience 2Pac BM1384 Stickminer Official Support Thread
Not all 2Pac were built the same. Same voltage, but one throws many HW errors, another does a few HW errors, and the last one throws 0 HW errors. This is why I asked if I could run each device with their own frequency (Mhz). Rather than device number, the serial number seems like a better unique identifier and maybe use the GSx hardware model if necessary. Maybe something for cgminer-gekko 4.11 
I don´t know if it´s common here, but I use the deb package screen to login to a session via SSH. With screen you can keep the session running even if you log off. When reconnecting you can resume the session with the command screen -r. I don´t know if cgminer is able to run two instances in two different sessions. If it is you could start two instances with two frequencies. Otherwise I would git clone cgminer in a second folder, maybe cgminer2, and compile it there. Then maybe you could start two cgminers in two sessions using screen.
