Sumeet,

Yep you are correct.  However what I'm trying to say is that if the
adapter is Bluetooth 1.2+ compatible and implements Add Sco Connection for
backward compatibility, then the faster eSCO alternative will never be
used.  Most of the Bluetooth 1.2+ USB adapters I've had experience with,
do implement the Add Sco command for backward compatibility.

Shouldn't we try to query the Adapter version first and then use the
commands which are appropriate?
