Hum... what happens when you attach a USB device to the computer? Kernel

You are talking about *devices* here.
I would have thought that something similar happens with an ethernet
device but I've lost the track to udev development and currently I would
not put my hand in the fire for what and how it does.
An ethernet cable is not a device.
But I like your turn of phrase. Go on, get your fingers burnt! udevadm(8)
and unplug and plug the cable back in. See any reaction from udev?
The question remains - Why would plugging or unplugging the ethernet
cable be expected to bring the interface up or down?
This sounds like a job for ifplugd
"ifplugd is a daemon which will automatically configure your ethernet
device when a cable is plugged in and automatically de-configure it if
the cable is pulled out. This is useful on laptops with onboard network
adapters, since it will only configure the interface when a cable is
really connected."
Caveat: I've not used ifplugd myself, I have a couple of custom scripts
that do various things depending on which interface (Wired/Wireless) is
available.
