The system will monitor it itself. :-)
My question to you would be: What exactly do you mean by
"automatically detect"? The drive *is* automatically detected.
Should it be mounted afterwards?
The creation of the device files (after system startup) is
controlled by the file /etc/devfs.rules.
You can use automounters to automatically mount devices when
they appear. In order how to determine file systems, slices
and partitions on such an USB device, you could, for example,
have a look at how FreeSBIE does it.
Additionally, there are already tools integrated in KDE and
Gnome that automount USB devices.
