If the Pi remains powered continuously and is able to power cycle the port* 
how does that not resolve?

*as described here: 
https://github.com/weewx/weewx/wiki/FineOffset%20USB%20lockup

What I don't know yet is how the config changes listed on the wiki (above) 
can relate to code used to control YKUSH. But I had a more important 
question about whether or not there is any back power from the USB ports 
which could damage the Pi (and have inquired accordingly). I'm assuming 
that I'd connect the power + UPS to the YKUSH and power the Pi and FO on 
separate ports and have the YKUSH reset the FO in the event of lockup.

On a separate but related matter I'd quite like to see the Pi optionally 
clear the buffer & display as it collects records from the FO, but I can 
see a case against. Doing so would provide a quick visual indication that 
there was no data backed up.
