It's the same model for both. If you plug-in a USB cdrom device, you
might only get 'add'. 'Change' is reported for media changes when the
device stays around but media is removed or added. 'Change' is also
used for USB disks not only for optical drives, where the media can be
removed, like USB card readers.

That's a one-shot command, not a switch to enable something in the
daemon that keeps polling. It should act on a specific device only.
