Hi there, I have just applied some Windows Updates today (), and have found that my USB Bluetooth dongle has stopped working. It was working fine before the updates, but now all I have is the device in the Device Manager list, showing Bluetooth Radios, then CSR Bluetooth 3.0 with a question mark next to it. The updates I applied are: - Cambridge Silicon Radio Limited - Audio, Other hardware - CSR BlueCore Nanosira and then immediately after came this one: - Cambridge Silicon Radio Limited - Audio, Other hardware - CSR Bluetooth 3.0 Now I am unable to roll back the drivers, and after a trawl of the Internet I can't find a replacement. Please can anyone let me know if they have experienced the same issue, and if they have been able to find a resolution? I was about to play l4d2 when I saw the 'Windows update' notifier pop up and let me know that there were updates to install, so I did (stupid me, I should know better by now). One of them was the new CSR Bluetooth driver update.

After installing the update, I noticed that my USB Bluetooth transceiver was no longer being recognized by the system. It was showing up as a: 'csr_btport_01', which 'Windows Driver Update' could not find a driver for!

I then Googled the problem and came across this thread. I am very angry that Microsoft would not take the time to see if a driver update that they are going to release would brick any function of a system! I hope that MS will notice the huge problem they have caused and release a fix ASAP! More info: Yes My OS is 100% Legal!

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 1.0.5.0 from Cambridge Silicon Radio Limited installed.

Windows was claiming that the device was working properly. Bose sounddock serial number lookup. 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. Chertezhi frezernogo stanka s chpu.

This driver has worked fine since late august and after the latest security update on Win7 it has stopped working correctly. It can see the server and reports back it COM nr, but when opening we're back at the same problem as in summer 2017 - timeout even after.
