Vostro 470: Unrecognized Bluetooth Devices

Hi,

Vostro 470, Windows 7 64 bit

I have 2 unrecognized Bluetooth devices in Device Manager under Other devices:

Both devices listed as Bluetooth Peripheral Device

Both devices have this error: The drivers for this device are not installed. (Code 28)

Hardware ID for device #1 is:
BTHENUM\{453994d5-d58b-96f9-6616-b37f586ba2ec}_VID&00010075_PID&0100
BTHENUM\{453994d5-d58b-96f9-6616-b37f586ba2ec}_LOCALMFG&0045

Hardware ID for device #2 is:
BTHENUM\{936da01f-9abd-4d9d-80c7-02af85c822a8}_VID&00010075_PID&0100
BTHENUM\{936da01f-9abd-4d9d-80c7-02af85c822a8}_LOCALMFG&0045

I have installed the latest available driver for my system from support.dell.com:
Dell Wireless 1703 Wi-Fi + Bluetooth Driver
Version 9.2.0.514, A00
http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=C54GH

Windows Update cannot find the drivers either.

What are these devices, and can anyone help me find the correct drivers?

Thanks

Anybody know how to decipher a BTHENUM?

Have you tried to reinstall the Win 7 network driver for your WiFi+BT card?  

Which driver you install depends on which card you have, Dell Wireless 1703 Wi-Fi + Bluetooth or Dell Wireless 1704 Wi-Fi + Bluetooth. You don't need both.

If you're unsure about which card you have, click the System Configuration link at top right of that page and enter your Service Tag. It should give you a list showing the components that were installed when you purchased the PC.

I'm quite sure which card I have. As I wrote:

I should have posted this in the Networking, Internet, Wireless forum. I'll take care of that now.
