Hi everybody

Recently my old usb bluetooth adapter died because I pull it out while in operation.
Now I got a new one but it seem the old device drivers are stuck inside Windows 7's service list.
I can not get the new device driver to install correctly.
I captured two error dialogs showing the device driver can't be installed because of the same name.
Bluetooth Remote control device
Bluetooth stereo audio
Any windows gurus help me out here please, I don't want to reinstall the os because of this.

USB is a hot pluggable standard. The hardware shouldn't fail, simply because you pulled it out while it was operating.

In the case of Bluetooth, you may have to re-pair your adapter with your device to reestablish connectivity. Have you tried pairing your devices again?

Did you attempt to uninstall the old software for your original adapter before you installed the new? You might have a look in the Start menu under All Programs to see if you can find software for your previous adapter that can be uninstalled, and also check in the Control Panel, in Uninstall a Program.

Thanks for your replies.
I uninstalled the old software (Broadcom) and refreshed in device manager and it found the Bluetooth stereo audio.
However, since I was messing with HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ I deleted one of the CSR key without backing it up.
I remember it could have been a Bluetooth remote control device driver coming from \system32\drivers, I remember the file name starts with B. But it could have been bthav.sys or BthAvrcp.sys
Do you mind checking your registry for a CSR key under that sub key?
Probably if I import this key the other device driver would install.
The HW ID for this device driver is {128CFE23-5667-45db-9C1B-23370DA73831}\CsrAVRCP_110E
Here are two screen captures of the device driver.

I can look, but the only Bluetooth enabled machines I have are not Broadcom...

No CSR in my registry, sorry.

Do you possibly have any System Restore points from around before you lost Bluetooth connectivity, or before you modified the registry?

Have you tried right mouse-clicking the Bluetooth device in your Device Manager and choosing uninstall from the context menu? It may present you with a checkbox on the confirmation page to remove the driver at the same time. Check the box to remove the driver if available, and then see if you can install the new device.

I don't use system restore.
But as long as the audio is working I am happy.
Thank you for the help.
