Question.  There are (at least) two different ways to mount removable
media.

1) Is there an entry in /etc/fstab for it?  If so does it have the
"user" flag on it?  Here is a typical entry for a cdrom showing the
"user" flag.  And a custom entry after it also showing the flag but
that entry isn't a standard one.

  /dev/cdrom      /media/cdrom0   udf,iso9660 user,noauto     0 0
  /dev/sdg1       /media/usbdisk  auto    user,noauto,noatime     0 0

The "user" flag is what allows the mount to happen as the user
invoking the mount command.  In which case the owership and permission
is the same as that of the invoking user.

2) If nothing like the above /etc/fstab entry exists then some desktop
session daemon is automatically mounting the media for you upon
insertion.  Such as the gnome-volume-manager.  In which case you would
need to find out which daemon is doing it and configure it.
