    Il n'y est pas non plus dans la liste si je rajoute un --all. De ce que j'ai compris, pour certains équipement, ils n'apparaissent que s'il y a une rule udev rajoutant TAG+="systemd". Dans mon cas, de plus, le chemin du device dans l'arbre de udev dépendant du port usb dans lequel je l'avais branché. Il fallait donc prévoir tous les cas.
