In Ubuntu 22.04.2 I am trying to add an previously existing USB-Ethernet adapter as follows:

but when I click on "Apply" it is not added. Nothing has changed. No new entry has been created. The screen looks like before:

I even tried to do that as root, but the adapter simply was not added.

Is that a bug in Ubuntu? In the settings? Is there a workaround? Is there a command line command chain to add such a USB-Ethernet device to Ubuntu so I can use it?

Content of file /etc/NetworkManager/NetworkManager.conf:

[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
[device]
wifi.scan-rand-mac-address=no

Is the adapter connected? If the adapter is not connected the system won't show it in the settings. – Thomas Ward Oct 24 '23 at 14:07
Yes the adapter IS connected, 100% perfectly sure! – Alex Oct 24 '23 at 14:11
It seems it works when I change the managed to true and restart the network. But even then it worked for some seconds, then it stopped working before it started working again after a minute or so ... – Alex Oct 24 '23 at 14:22
Does this answer your question? My wireless/WiFi connection does not work. What information is needed to diagnose the issue? – waltinator Oct 24 '23 at 15:41
@waltinator No, my issue has nothing to do with a wireless device whatsoever. – Alex Oct 24 '23 at 15:57
