Je ne comprends pas pourquoi, quand j'ai essayé un plug-in de pilote USB externe dans Ubuntu 12.04, je vois le message suivant:
Error mounting: mount exited with exit code 1: helper failed with:
mount: only root can mount /dev/sdb1 on /media/sdb1
Voici le contenu de /etc/fstab:
# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
