Even worse, some UPS USB chips reconnect on every self test, for example
APC (although APC at least has a proper serial number).

And if you think dealing with serial free UPSes is bad, we had some
printers with no serial number.  Interesting user interface ("I see 
a new USB printer.  What printer did you just plugin or turn on?")

After a few years, we laid down the law:  we do not support USB devices
with no serial number (they are pretty much only useful on a single user
system).
