Bonjour à tous
Je possède un appareil photo numérique Canon EOS 300D. Je souhaiterais récupérer les photos depuis l’appareil via un cable USB avec gphoto2. J’utilise une debian sarge.
Je ne suis même pas e mesure de lister les fichiers présent sur la carte de l’appareil.
A la commande gphoto2 --debug -L en tant que root (pour être sûr d’avoir les permission read/write) j’obtiens l’erreur suivante :
