Thanks.  I added a few lines to /e/n/i and everything works just fine
now.  The actual lines are

,----
| # the USB network for my Gemini
| auto enp0s29u1u1
| iface enp0s29u1u1 inet static
|   address 10.15.19.80
`----

and I simply "sudo ifup enp0s29u1u1" when I need it.

But I still do not understand why it works automatically on one of the
systems but not the other.  One of those mysteries, I guess.
