Impossible de monter ou de reconnaître le lecteur flash USB Ubuntu 14.04

Question

Je ne parviens pas à monter mon lecteur flash USB 16.0 de 16 Go à la fois sur Windows 7 et Ubuntu 14.04.

L'appareil ne s'affiche pas sur fdisk ou lorsque je lance lsusb.

C'est ce que je reçois lorsque je lance dmesg après l'avoir branché. Toute aide sera grandement appréciée.

Je ne sais pas si c'est lié, mais la première fois que j'ai essayé de l'utiliser, j'ai eu un crash sur Ubuntu.

Answer 1

Si votre clé USB a des problèmes sous Windows et Ubuntu et qu'elle se connecte/déconnecte/se connecte/se déconnecte/... tout le temps, il semble que le circuit de contrôle de votre clé USB soit tombé en panne.

Pour être absolument sûr:

1. essayez un autre périphérique USB sur le même port (imprimante clavier/souris/...)
2. Éteignez complètement la machine, coupez l'alimentation et les piles, rallumez-la pendant une seconde, insérez de nouveau les piles et l'alimentation, allumez-la et essayez à nouveau

si 1 fonctionne et 2 échoue, jetez la clé USB et achetez-en une nouvelle.
