Since they are all USB-to-RS232 adapters, you can't tell anything by USB
info (they are all interfacing to RS232 devices).  Two of them use the
same driver, and annoyingly, the chip vendor for that USB-to-RS232
doesn't set a serial number, so the only way to distinguish them is via
USB port.

Also, some GNOME thing is not a solution, as I'd like my UPS and GPS to
be active on boot (the GPS is used by NTP for clock sync), not some time
later after a user logs in.

So then we have to have two things running trying to name devices?  I
thought udev was supposed to be "the" solution.  Using udev rules is
easy, it is just that writing them is beyond the point-n-click user.
