You have an HP notebook/laptop computer that has a built in Blue tooth adapter. However the device either shows up as unrecognized in computer management, or you are unable to connect to blue tooth devices.
Checking the computer management console you will find that you have an unknown or unrecognized device with the Device ID of "USB\VID_03F0&PID_011D".
Cause of the Problem:
HP does not offer a downloadable driver for this blue tooth device. The device driver must be installed for the device to function correctly.
You must either purchase a copy of the HP restore CDs or do the following work around to manually install the driver.
To manually install the driver:
Find the bth.inf file under C:\windows\inf
Open the bth.inf file and find the following section
Device section - Start and then under that find
Microsoft Wireless Transceiver for Bluetooth=...
Microsoft Wireless Transceiver for Bluetooth 2.0= ...
Add the following lines of code directly after the last entry in that section.
HP Integrated Module with Bluetooth Wireless Technology= BthUsb, USB\Vid_03F0&Pid_011D
HP Integrated Module with Bluetooth Wireless Technology= BthUsb, USB\Vid_03F0&Pid_171D
Save the bth.inf file, and uninstall and re-install the device through the Device manager window.
Doing this should cause the blue tooth adapter to be recognized properly and install the additional drivers associated with it.
