This is a feature request I've already discussed shortly with Etienne
Goyer.

Setting as Wishlist/Confirmed since I can acknowledge the issue, except
there is a lack of easy ways to fix this.

Thinking back however, I'm certain there is a way of at least patching
NM so that the default wired connections usually created automatically
would not be, which will allow you to have new devices not automatically
build connections and activate, but still allow creating them manually
when needed. Since patching this is possible then it should be
relatively simple to also make that optional and dependant on a
gconf/dconf key (which would default to the current behavior).

Title:
  Network Manager option to avoid auto-enable of new network devices

Status in “network-manager” package in Ubuntu:
  Confirmed

Bug description:
  This is a feature request.

  It would be nice if Network Manager could be configured such that it
  won't automatically attempt to use new network devices attached to the
  system.

  Here's the reasoning.  My team manages a large fleet of enterprise
  desktops.  We've had a number of cases where a user plugs a USB NIC
  into their computer, and Network Manager helpfully configures the new
  network interface and runs dhclient on it.  And if the DHCP response
  is answered, you get a new default route, new resolv.conf, etc.  In a
  couple cases this was caused by plugging in an Android phone that had
  USB tethering turned on, and I think we even had one case where
  plugging in a USB GPS did this.  None of the cases involved the user
  actually intending to use the device as a network interface.

  We could blacklist the usbnet module, but there are legitimate cases
  where we want to allow USB networking.  It would be so much better if
  we could get Network Manager not to use these new devices that have
  shown up until the user configures them.
