You still didnt got the most important point..

_one daemon instance for each device_.

1. The first thing that we will do is attach to the usb port. We need
it to get the serial number, so the daemon can decide which .conf file
to use and/or which plugins to load. :)

2. When you unplug the device, his controlling  daemon exits.

3. When you plug another device, a new daemon is called.

Daemon is kind of a bad term. It is more a hotplug loaded driver, and
*not* an always running daemon.
