What I remember from talking to Steve at Warpstock in 2004 about it was that it was basically a matter of Mark debugging the card to get the information needed to create a USB driver for it.  It was quite awhile ago and Stu can answer this part better than I but I think the card is seen as a network card and doesn't require a connection manager but it could be that I forgot that or it just wasn't mentioned in the conversation.
