Abstract

Des exemples de l'invention permettent de déterminer si les capacités d'un dispositif peuvent être supportées par un port d'un autre dispositif, tel qu'une station d'accueil. Dans un procédé donné à titre d'exemple, un premier dispositif identifie les capacités d'un premier port du premier dispositif et identifie les capacités d'un second dispositif connecté au premier dispositif par l'intermédiaire du premier port. Le premier dispositif détermine si les capacités du second dispositif peuvent être satisfaites par les capacités du premier port du premier dispositif. Si les capacités du second dispositif ne peuvent pas être satisfaites par les capacités du premier port du premier dispositif, le premier dispositif affiche une invite pour connecter le second dispositif à un second port du premier dispositif qui supporte les capacités du second dispositif.
