I believe this is fixed in Focal. Can you check if this is still an
issue for you with a current image from
http://cdimage.ubuntu.com/releases/20.04/release/?
After rebooting a Pi running a current Focal image I get (on the
connected host):

And after loading g_{cdc,ether} on the Pi:

And the connected host reports:
$ lsusb

So from my POV this looks as good as it gets. Please confirm.
