    fstab entry doesn't mean that file system is mounted.

    As you see, mount point is different from entry in fstab.
    Generally, you don't need an entry in fstab for the camera on 9.1,
    the mount point is created dynamically by hotplug.

    Are you using standard 9.1 hotplug or did you disable subfs?

    If it's standard unchanged hotplug, then after connecting your camera
    you should see something like this in your /var/log/messages:
    (I'm using latest updates from YOU, hotplug-0.44-32.22 and submount-0.9-33.6)

    Mount command should now report your camera mounted at a dynamically created mount point:

    mount

    /dev/sda1 on /media/usb-storage-000242727020:0:0:0p1 type subfs (rw,noexec,nosuid,nodev,sync,procuid,iocharset=utf8)

    The directory name will be different in your case, most probably it will be
    /media/usb-storage-000000000002:0:0:0p1

    If you cannot access your camera at this point (try something like
    ls -l /media/usb-storage-000000000002\:0\:0\:0p1) and it's reported as mounted,
    then for diagnosing purposes unmount it manually with command:

    umount /media/usb-storage-000000000002\:0\:0\:0p1

    and then mount it manually:

    mount -t vfat /dev/sda1 /media/usb-storage-000000000002\:0\:0\:0p1

    If you can access it after that, then it means some problem with subfs/submountd.
    If not, the problem is at some other layer.

    I don't know if this procedure will help you, at least it provides some guidelines
    where to look.
