Apollo II never stop mining even when no pool connected/no mining software is active

[github12101]

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. Apollo II never stops burning electricity for nothing, even when it supposed to be idle.

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

I am using latest available binary on Linux AMD64:

./apollo-miner-v2 --version
apollo-miner 2.0.2 2024-05-18, msp ver 0xd167
Use "--help" switch to print command line options.
