      What is handling the insertion notification ??? hotplug ??? are you running
      devfs or udev ??? is your machine trying to bring up the network before the
      underlying support for the card is activated ???

      I understand what ping is. What I don't understand is why I would try
      it when I have no network. If there are no connection lights on the
      dongle, then I have no networking. I would assume that, even without
      networking active, if I pinged the loopback then I'd get an answer.

      Either the network is working or it isn't. If it works it's because
      of the process that I described below. What I'm trying to figure out
      is why the network card doesn't work if I leave it in during boot up
      vrs. pulling it out until a certain time during bootup.
