the code above i.e.
iface lo inet loopback
iface eth0 inet dhcp
is from /etc/network/interfaces.
So it has nothing to do with any mounting.
The Hotplug (dev) handle the permissions. You can access or modify them with defining the rules for hotplug located into /etc.
usbmount is an app that does help you simply in mounting. I have never installed it, nor used it. It is really not necessary.
