Windows XP SP2 comes with its own Bluetooth stack. If one uses it, one
cannot use the drivers that come with the USB-BT adapter, all made by
Widcomm. (I don't know if Widcomm actually makes the Microsoft version as
well, but it's quite different.)
Which do people find better? Does the Microsoft stack support all the
profiles? I know some programs say they only work with the Microsoft stack.
