The question seems to be about USB protocol/packets, not really end-user stuff. There really is some mode change magic, Nokia Suite is also capable of changing connection mode (from anything to Ovi/Nokia/PC Suite mode).
In older days there was a connectivity related board, now it is archived but you can check if you find there something: http://www.developer.nokia.com/Commu...faces-(Closed)
