Souris fonctionnelle.
Edit : La souris permet de recevoir sur deux canaux en BT à sélectionner manuellement (utile pour travailler sur deux ordinateurs différents ou deux OS différents et un canal branché sur le dongle "Unifying" propre à Logitech. Ce sont peut-être ces trois ports classés comme "Human Interface Device", je suppose.
