Windows 7 Home Premium x64

Thank you davewebb8211!
That solved my problem too.
I've tried switching between drives before but I haven't noticed that there was another device under USB controllers.

Now I can use my headset again, thank you again.

I tried the solution suggested by davewebb8211, but to no avail. Instead, I decided to restore to an earlier point and this resolved it. On my Windows Update history, the dodgy driver updates are showing as having been installed, so hopefully it won't happen again.

Thanks for all the help!

I ran into the same problem* but I found a solution for me I'd like to share with you.

For me, uinstalling the driver didn't help.
In the device manager I have the "CSR_BTPORT_01" entry under "Other devices". It had no driver installed and Windows added an exclamation mark to the device. Trying to find a suitable driver did not succeed (Windows Update, manual selection, etc.)
The second device was "CSR BlueCore Nanosira" under "Universal Serial Bus controllers" which had a new driver from 2011-01-13 with Driver Version from Cambridge Silicon Radio Limited installed. Windows was claiming that the device was working properly.

You see my situation in screenshot 1.

My solution was to change the driver of "CSR BlueCore Nanosira" under "Universal Serial Bus controllers" back to the generic Bluetooth driver.

To accomplish this select "Update Driver Software" from "CSR BlueCore Nanosira" (the working device), then select "Browse my computer for driver software" and then "Let me pick form a list of device drivers on my computer". In my case Windows presents the new driver from CSR ("CSR BlueCore Nanosira") and two generic drivers as you can see in screenshot 2.

I selected "Generic Bluetooth Radio" from the list and clicked OK. Then I had "Generic Bluetooth Radio" and "Microsoft Bluetooth Enumerator" back under "Bluetooth Radios" and the Bluetooth icon appeard in the taskbar again. After that I was able to use my bluetooth mouse and keyboard again (even without pairing it again).

Hope this helps for you, too!

Best regards

* I accepted the update of the bluetooth driver by Windows update because I have some problems (unresponsive mouse) with Windows 7. The identical (!!!) hardware works flawlessly with Linux (in my dualboot configuration). So I was hoping for some improvement.

F'n brilliant!

Windows optionial Bluetooth driver update.....Fix

I too lost access to my device after the optional CSR Radio Bluetooth update. If I removed the driver, it would just auto load in the non working update.
My solution:
Disconnect from the net. May not need to do this, but better safe.
Control Panel
View Devices
Right Click Bluetooth Radio
Click Properties
Select Bluetooth Radio
Click Properties
Select Driver
Select Roll Back Driver
Connect back on the net

My Bluetooth Device is back to where it was.

Microsoft Windows 7 Home Premium 32-bit 7601 Multiprocessor Free Service Pack 1

Hi All.

I had the same problem after accepting this update.Way to go Microsoft!
The only driver i could find was Toshiba Bluetooth stack v 8.00.05 which was okay BUT
it was a 30days trial.So searching a little more i found the v 7.00.08,that is for free and it also works good BUT only for up to 2.1 bluetooth devices.I am very curious to see the Microsofts solution for this.

Thats all folks.

If your Bluetooth mouse quits working after an update, try the following.

Go into Control Panel -> Device and Printers and see if there is a mouse (or 2) already there. If so, right click on the mouse picture and Remove it. Repeat for all of the phantom mice.

Reboot and try the discovery process again.

Works on Vista also.
