The problems is with using bluetooth "S60 3rd Edition Feature Pack 1" onwards requires to load a driver which cannot be easily unloaded. The operation of bluetooth adapter while being used with Nokia Connection Framework (NCF)prevents use by PC Suite.

Device information

To support the new Belkin 2.0 EDR Bluetooth adapter.

The file in the path in Windows XP at %systemroot%\inf\bth.inf will need an addition of an extra line.

Belkin Bluetooth Adapter= BthUsb,   USB\Vid_050d&Pid_0081
Belkin Bluetooth Adapter= BthUsb, USB\Vid_050d&Pid_0084
Brain Boxes USB Bluetooth Adapter BL-554= BthUsb,  USB\Vid_05d1&Pid_0003
Blutonium Belkin Bluetooth 2.4 GHz Single Chip Transceiver= BthUsb, USB\VID_050D&PID_0013 
;Added Belkin 2.0
Blutonium BCM2035 Bluetooth 2.4 GHz Single Chip Transceiver= BthUsb, USB\VID_0A5C&PID_200A
BCM2033 Bluetooth 2.4 GHz Single Chip Transceiver= BthUsb, USB\VID_0A5C&PID_200F 
Generic Bluetooth Radio= BthUsb,   USB\Vid_0a12&Pid_0001

CSR Nanosira-Multimedia=  BthUsb, USB\Vid_0a12&Pid_0005

This is an excert from the file bth.inf. The bold section above is the part entry added to detect the Belkin 2.0 EDR.

The WIDCOMM driver software has not been loaded to allow the Microsoft (MS) Windows XP to detect the bluetooth device. This will allow the Belkin device to work in 1.2 compatability opration.

S60 drive installation

After following the steps above for Belkin 2.0 EDR Bluetooth Adapter install the driver for the SDK using instructions in the manual. S60 3rd Ed SDK Bluetooth driver

Second Adapter inforamtion

The second bluetooth USB adapter should be from another manufacturer, in this case this was from Cambridge Silicon Radio (CSR) chipset which is on the Microsoft list of compatible bluetooth devices.

The S60 3rd Ed Bluetooth driver has now left an empty slot. The second device the CSR bluetooth adapter has now taken over the empty slot. When PC Suite is started the CSR device is now use and connect to a bluetooth phone. The phone being used to connect to bluetooth can only connect to one adapter at a time. The phone can hold pairing to both devices.
