ATM it is running from the command line as I did not want to reboot the Pi:
/home/weewx/monitorlockup &
I have also added that command line to /etc/rc.local so that the script
will start on reboot.
The monitoring script sits in the background waiting for a log print. When
weewx writes to the log file the script wakes up and checks the new log
line(s) for "Errno 110". If the string is absent the script goes back to
waiting for the next log print. If the print is an error line then it
fires off the second script to powercycle the relevant USB port.
You can watch it come alive every 5 minutes with `top(1)`.
Obviously, you will need to have acquired and built the source of
`uhubctrl` in advance.
