Unable to connect to Bluetooth USB Dongle Cambridge Silicon Radio Ltd

OK, I've just discovered the same problem. This occurs frequently and I've seen similar threads.

I think it's about time MS got their head around this.

In my circumstances, my son bought himself Bluetooth headphones. I dug out a (fairly) recently purchased BT adaptor, plugged it in and Win 7 64bit (all updates) found a driver and installed it. It was a Realtek driver dated Dec 2014.

However, once installed, no Bluetooth Properties appeared. Device Manager showed the CSR Bluetooth Radio, but no Microsoft Bluetooth Enumerator appeared.

I tried to find an appropriate driver and installed one. It installed CSR Bluetooth Stack but failed to complete (the drivers were installed, appeared in Device Manager, but would not perform).

I further investigated and found references to the inbuilt Generic Bluetooth Driver in Win 7 and that many had successfully deployed that (Update Drivers, Browse Locally, Pick from device drivers on my computer).

That didn't work properly.

I tried the same process on my office computer, and the auto installed Realtek Driver didn't work. But the generic driver did.

So I have now established that both components (Win 7 64bit & CSR BT dongle) can operate successfully together.

But I cannot perform a System Restore to go back to failed BT driver install. (And that's the only Restore Point it thinks is there.)

I'll experiment more - I just don't know why Microsoft have deployed an Auto Update that screws up something that was working fine!

Hi all. 

I encountered the exact same problem. I almost gave up and just wanted to smash my csr bluetooth chip with a hammer.  BUT I've found a solution - and it's simple! I'm actually writing this post on my rapoo bluetooth keyboard :)

My settings are not english, but I'll try explaining:

1. In "Device Manager" find "CSR Bluetooth Chip/radio" (there is a bluetooth symbol) right click it and choose "Settings".
2. Click on "Driver" and choose "Update driver". 
3. A new window pops up. Choose the last option. Should be something like "Look through the computer for drivers" or "Search computer for drivers"?
4. Next you have the option to choose a path for the driver - ignore that. Instead click the last option. Should be something like "Let me pick from a list of device drivers on the computer" or something like that. 
5. Now you can choose between compatible drivers. On my screen 4 drivers are available and "CSR Bluetooth Chip" is chosen. Just double-click on the last driver "Generic Bluetooth Radio" and click next. 

Now the driver should install and the bluetooth icon should appear in the process bar. Right-click it and pickadd a device. After 10-20 seconds my keyboard appeared and I was able to pair with it. (Remember to make your device visible to other bluetooth devices) 

I hope this helps! It solved my issues :)

Installed and directly recognized my MDR-1RBT blutooth headset and other devices as well.

Hope it will solve your problems with your Bluetooth dongle with CSR8510 A10.

Encountered the problem too. I was able to solve it for me, maybe it works for you too.

PS: I use the german Version of Windows, so i just guess what the Setting and program names are in english.

1. Uninstall the CSR software and driver
2. Go to "Device Settings", right click on the Bluetooth Radio -> Settings.

 ->Select "Uninstall Driver" and check the box at the bottom "Delete Driver for that device"

3. Reboot
4. Reinstall orignal Software/Driver that came with the stick(or download from their homepage

Done, should work right away, if not, reboot. And skip the Windows Realtek update if it ever comes up again :)

I hope this will work for you. Good luck.
