Comment 21 for bug 360160

@Githlar: If you upgraded from an earlier version of Ubuntu, then there will be a mountdevusbfs.sh.dpkg-dist file in your /etc/init.d/ directory. Create a backup copy of the existing moundevusbfs.sh, and then replace it with the dpkg-dist file. If you don't have a dpkg-dist file due to some reasons, please download the file attached to this post, and copy it to /etc/init.d/ with 755 as the permission and root as the user and group of the file. At the same time, comment/remove the hack in the /etc/fstab, and then reboot.
