Device: Apollo II standard USB unit, first batch

Problem: device never stops mining (I can feel the heat coming out of the vent and fan is spinning quite loud), even when pool is down, or mining software apollo-miner-v2 executable is not running on connected (via USB) computer

Apollo I did not have this problem, and I can disable mining program and device will cool down quickly. I use it with a script and thermometer to turn on and off Apollo I when needed.
Apollo II never stops burning electricity for nothing, even when it supposed to be idle, I can't temperature-control it, it's just working non-stop.

Please tell me how can I tell it to stop burning electricity for nothing?

I am using latest available binary on Linux AMD64:
