Bonjour
Je remonte ce sujet, car j'ai aussi des problèmes au niveau des transferts usb de mes fichiers. Lorsque je transfère des fichiers sur mon lecteur mp3 (à partir du DD ou d'un des mes disques externes) il arrive fréquemment que le taux de transfert descende à 0, avant de repartir quelques minutes après). Quant au lecteur de carte mémoire intégré à mon portable, lors des transferts de la carte vers le disque dur, le processus utilise presque tout le CPU du pc
J'ai pas mal googlelisé et apparement personne n'aurait encore trouvé la solution ?
Voici mon lsusb
[root@localhost ~]# lsusb
Bus 002 Device 006: ID 071b:0184 Domain Technologies, Inc. ==> correspond au lecteur mp3
