Abstract

La présente invention concerne un dispositif et un système de communication, et un procédé de communication. Le dispositif de communication est pourvu d'une interface USB, d'un terminal mobile, d'un circuit de commutation et d'un circuit de commande logique. Le terminal mobile délivre en sortie un signal de validation si le terminal mobile est dans un état de mise sous tension et reçoit un signal d'activation, puis le circuit de commande logique commande, en fonction du signal de validation et du signal d'activation délivré en sortie par l'interface USB, le circuit de commutation pour connecter ou déconnecter un trajet de connexion entre l'interface USB et le terminal mobile. Le terminal mobile délivre en sortie le signal de validation uniquement lorsqu'il est à l'état de mise sous tension, et est connecté à l'interface USB en combinaison avec le signal d'activation délivré en sortie par l'interface USB, de sorte que la situation dans laquelle le terminal mobile est activé et chargé une fois qu'un dispositif USB externe est connecté à l'interface USB est évitée.
