NetworkManager was included with the Ubuntu Studio 19.10 installation (via bootable usb). Netplan's cloud-init (below) was the first route of repair, but did not do the trick and netplan.io was purged in the troubleshooting process:

After manually modifying: ``` unmanaged-devices=*,except:type:wifi,except:type:gsm,except:type:cdma,except:type:ethernet ``` the USB/ethernet adapter is detected and configured automatically by NetworkManager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1885127/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
