new device uses com port from already registered device

Hi guys,

I have an application that can collect data from different Bluetooth devices.
I have a dongle with the WIDCOMM BT stack. Unfortunately when I register in new device to my Win XP Prof SP3 computer, it uses the same COM port as another device. This other device no longer can communicate because of this. If I remove and add the old device again, it works, but then the newer device will no longer communicate.
Apparently I cannot manually choose COM ports in the WIDCOMM stack? Anyone any ideas on how to solve this?

In case anyone should need this in the future: I found the solution: I added a COM port manually in the Bluetooth configuration (right click notification area icon>Bluetooth configuration). Click on the Client Applications tab and Add COM port. First unpair both devices, then repair using a different COM port for both of them.
