Vista - What is Bluetooth Peripheral Device?

I have a HP Compaq 6715b notebook with Vista Business, the OS preinstalled from HP. For some time ago I connected my Sony Ericsson mobile to the PC as a new Bluetooth device. During the installation, I was prompted to install missing drivers for devices named "Bluetooth Peripheral Device". I never found any drivers, and finally I ignored it. The installation was successful as far as I can see, I have never noticed special problems. However, when I look into My Computer > Device Manager, there is a listing under Other Devices, 2 "Bluetooth Peripheral Device" and 2 "Unknown Device", in total 4 devices, all missing drivers. A quick look at Google tells me that there are many others with HP machines in the same situation, HP obviously does not install these drivers for some reason. I contacted HP support in Scandinavia, but they didn't know anything about Bluetooth Peripheral Device. I see further in Device Manager that there is a HP Integrated Bluetooth module (together with Microsoft Bluetooth Enumerator), maybe these are substitute for the "Bluetooth Peripheral Device"? Can anybody tell me more about this? Do these missing drivers exist, are they important, or should they just be ignored?

If communications betwwen cell phone and computer fully work this is only small installer issue.Make sure you have the newest drivers HP Compaq 6715b Notebook PC*-* Support Software for HP Integrated Module with Bluetooth Wireless Technology (Microsoft Windows Vista) - HP Business Support Center
If yes and still the you have the same problem you have to modify installer this means you have to modify *.inf file in installer add Hardware ID of orphans and again install

Reading Hardware ID

Open device menager
right click on empty devices>>properties>>details>>find Hardware ID

read it and post here.

EXAMPLE

Suppose these missing devices have following hardware ID

1.Unpack InstallShield installer (just double click on it),choose location for unpacked files.
2.Navigate to Win32 folder (if anybody have x64 system then have to choose Win64 of course) and find btwavdt.inf,open it

find [WIDCOM] section,next find BTWAUDIO subsection

and add line in following rule

%BTWAUDIO.DeviceDesc<number>%=BTWAUDIO,<hardware ID>

Above examples in hacked btwavdt.inf looks below:



Save hacked file.
3.Uninstall drivers for bluetooth and install the hacked one.

Good luck

Hi,
Tanks for your reply. I downloaded and installed the new driver you mentioned, everything OK. I installed my mobile phone as a new Bluetooth device, all the relevant drivers were installed correctly. However, at the end of installation Vista once again asked for drivers for "Bluetooth Peripheral Device", exactly what happened to me earlier, and 3 new "Bluetooth Periferal Device" without drivers showed up under "Other Devices" in Device Manager. I ignored it now, this is not a problem for the Bluetooth communication between my mobile and my PC as far as I can see. Later I will have a closer look at your hacked "btwavdt.inf".
Once again, THANK YOU!

Flavius,
are you still there? I hope so. Sorry, I have been very slow, I hope you are still available. These are the hardware ID's reported with missing drivers of the 2 Bluetooth Peripheral Devices I have found:

Bluetooth Peripheral Device (I):
BTHENUM\{8e771301-0000-1000-8000-00805f9b34fb}_VID&00010000_PID&c0efBTHENUM\{8e771301-0000-1000-8000-00805f9b34fb}_LOCALMFG&000f

Bluetooth Peripheral Device (II):
BTHENUM\{8e771401-0000-1000-8000-00805f9b34fb}_VID&00010000_PID&c0efBTHENUM\{8e771401-0000-1000-8000-00805f9b34fb}_LOCALMFG&000f

As a layman, I would really appreciate if you could give me your comments and recommendations in order to fix this strange problem.
So far, I look forward to your reply.

You have to add only signed red color.Probably your btwavdt.inf will be looks like as here:


EDIT

If you have any problems show screen from your btwavdt.inf file
