These scripts save significant power by shutting down HDMI, Ethernet, USB ports and connected USB devices.
To use them call buspower_up at the beginning of hive.sh and call buspower_down at the end of hive.sh.
WARNING! These scripts are in alpha testing and not for production release.
Oops, after running 24 hours, there were lots of hung processes:
