Last question, I swear. Does anyone else that is running the dualminer-cgminer on linux have a problem when switching to a different pool, and when doing so lose a couple usb miners that will not connect. For example I am running 16 dualminers, when I switch from pool A close cgminer, load pool B .sh file now only 12 of the dualminers show up. So I have to unplug all of them from the hubs, run dmesg then plug them all back in, run dmesg now connect again and all 16 show up and start mining. But when I decide to switch to another pool, not all 16 show up and I have to repeat the above step to get the all online again?
How are you closing your previous pool connection? Pressing 'Q' or just closing the terminal/ctrl+c? I have noticed this but usually when improperly stopping cgminer. When this occurs I just power cycle the hubs/reboot the machine. You could try to make a script that reboots in between switching pools if you want it automated.
