            Doing a little googling I found a comment that said you
              need to make sure modemmanager is disabled as it will
              think it's a modem and try to initialize it... Other than
              that you can try:
            

            $ tail -f /var/log/messages
            

            In a terminal window and then plug it in and look
              through any new output when you do so.
