Your network device name will be something like "/dev/enp0s20f0u4",
where the number of the USB port is part of that sequence.  If you use
a different port, it's seen as a different device.

It's not that intuitive.  We expect a device name to be associated with
the device.  Which is doable with some jiggery pokery, but it's far
easier to just keep dongles plugged into the same port.

To put that into context.  We expect our mouse to always been seen as
our mouse, no matter which port we plug it into.

I came across this when I recently unplugged my phone cable from the
computer, and didn't plug it back into the same port.  The cable had
been in the same port for months, and I hadn't really thought about it.
