Clearly the docking unit isn't just doing this flakily on its own.
Something is making it happen, and I've no idea how to discover what it
is except that it seems to be correlated with systemd in some way.
Just "thinking out loud" here.
When you run the script from the command line it is after you've determined the
unmount
has happened. How much time do you think elapsed between the actual unmount and
running of the script? Do you have a delay between the time inotifywait detects unmount
and powering down the drives? If so, does it help if you extend the delay?
I have never used it for this, but wireshark does have the ability to monitor USB.
Don't
know if that will reveal anything or be of any help.
