Good question, since there doesn't seem to be a serial number.

I think that I'd be inclined to have a section name in the config file 
that matched against various parts of the device identifier.  Perhaps 
it could be a tuple of vendor name, product ID, and port/hub number, 
where it did a best-match or a first-match.

I see that uhid(4) speaks of a "reportid".  What is that?  Does it 
apply to devices that are plugged and unplugged?
