Now that's a high quality user interface!  You have to choose an  
option to allow a device *you got in order to be able to access the  
Intarweb remotely* to be viewed as, err, umm, a network adapter.  It  
sounds as if somebody at Sprint, or whoever wrote the software that  
requires that option to be enabled, needs a visit from the UI Clue

No - if anything is, it's WinDump's "-D" option.  However, I wouldn't  
be surprised if that also failed.

However, my *suspicion* is that the broadband adapter looks like a  
dial-up adapter, which means that it *might* not show up until you've  
opened a connection, and that if you open the "Adapter for generic  
dialup and VPN capture" you can capture PPP setup packets on that  
adapter (or any other dial-up adapter) before the connection is set up  
and continue to capture the PPP traffic on the adapter after the  
connection is set up.
