Resolved problem with xp sp2
Dear fellows,
I had the same problem with xp sp2 to my bluetooth devices too. Sincerely sp2 works flawlessly with my Logitech bluetooth keyboard and mouse, but when I try to use my bluetooth headset xp sp2 can't recognise it. Surfing the internet I see this is a common problem, because sp2 internal bluetooth only support these devices, but not audio devices (headset, mobile phone). After several hours install and deinstall the widcomm bluetooth software trying to make sp2 recognises it, I realize that I must uninstall the internal xp drivers to get ride of this probl. Here is my howto:
1. Install the latest widcomm software 1.4.3.4
2. Patch the drivers, because widcomm is not xp certified at this time (use this link

3. Install the bluetooth software (my case Logitech bluetooth sofware)
4. Before reboot machine, hook up a wired mouse to gain access to windows later
5. Boot xp in safe mode
6. Uninstall these bluetooth devices in device manager
7. Reboot, remove the wired mouse to make xp recognizes the bluetooth devices
8. Work flawlessly. Now I have access to all my bluetooth devices as better supported by the proved widcomm bluetooth software.
Hopefully You can make used of my experience.
