Oh, thanks! This info and the command will help me at other places too.

And: Yes, also my two burners are listed when I submit this command on my
box.

But what makes k3b think there is no burner at all?

Instead there are a Plextor and one LG burner installed and
recognized.

What can I do next to fix that ?

Best regards
