How to configure onboard Bluetooth device

[u0000]

Hi all i have a iAtkos v7 - Leopard 10.5.8 working.

I want to activate the onboard Bluetooth Adapter

I already checked that plugging a USB Digicom external dongle works.

 

The onboard device is Cambridge Silicon Radio

Device Id 0x0001

Vendor Id 0x0A12

 

Since i have dual boot I found under Windows 7 that the device path is

 

PCI Root 0

PCI 0300

Usb Root 0

USB(3)

 

Altough i found references in the forum posts that device 0x0A12 should work as an external dongle it didnt' never show up in System profile under USB devices

 

No bluetooth device is reported in IOREG listing

 

I tried to modify the Info.plist under

 

IOBluetoothFamily.kext

CSRUSBBluetoothHCIController.kext

 

inserting Device id 1 and Vendor Id 2578 (hex 0x0A12)

 

Device doesn't show up :-(

 

What i have to do ?

Tnx for help.

Fabio.
