Hi nko
I was one of those people personally involved in the bluetooth driver wars with MS back when SP2 was first released. The problem: MS's initial BT release in SP2 was crap. And, it seemed no one among a loose nationwide alliance of techies (me included) could find a way to make XP install any BT driver other then its own. Until finally. Until finally, Mission Accomplished!
I recently helped a TS user who, no matter what she did, XP chose the wrong driver for her music device even tho she kept uninstalling drivers, disabling drivers, and trying to find ways to tell it the exact driver she was supplying.
So i'm willing to give it my best shot: Could you please walk through your problem again being sure to mention part numbers, driver versions, steps you took that failed, etc. Hopefully can help make sense of it for you.
