Dell Bluetooth software will not run on my Latitude D600 after installing XP SP2. I obviously tried everything mentioned in this forum:

- Microsoft BT-stack definately runs
- I installed Dell Bluetooth software A05
- Changed BT-driver in device manager successfully
- "Dell TrueMobile 300 Bluetooth Module" now is marked ready with WIDCOMM driver ver. 3.0.1.804
-FN+F2 allows switching it off and on again
- Dell bluetooth software always says "no bluetooth device available", BT-symbol in system tray is red/blue
- deinstalling software and driver makes Microsoft BT work again after reboot

Any idea?

thanks,
Jochen
