p.p.s I just noticed that I didn't have the subsystem prefix on my rule.
So my entry in 50-localusb.rules is:
SUBSYSTEM=="tty",ATTRS{serial}=="1344794749", ATTRS{manufacturer}=="Silicon
Labs", SYMLINK+="DavisVP"
and I rebooted; altho I still don't have a symlink for /dev/DavisVP
all the same my station is back online, submitting reports to all three
configured weather services
