The bluetooth drivers provided by windows don't provide all the services for the Cambridge Silicon Radio Bluetooth CSR8510 A10 adapter.
May 14, 2018 In the search type' Device manager ' and open it. Click on the small arrow next to either 'Bluetooth' or 'Universal Serial Bus controllers'. Right click on 'CSR' and select Update Driver. Select' Browse my computer for driver update'. Select on bottom 'Let me pick from a list of available drivers on my Computer'. Select 'Generic bluetooth Driver'. Then Windows tries and fails to find drivers with the error: csrbtportenumerateddevice00 No Driver Found. The device is also listed like that in Device Manager. Because there are no drivers, the device is not listed in the RealTek playback devices dialogue and the headphones obviously don't work. Update the device driver. In the search box on the taskbar, enter device manager, then select Device Manager. Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update. Select Search automatically for updated driver software. Select Update Driver.
After installing CSR's full drivers for this bluetooth device, and pair with the Blaze speaker, you then find theres 3 devices not correctly installed in device manager:CsrBtPort_Enumerated_device_00 Failed
CsrBtPort_Enumerated_device_00 Failed
CsrBtPort_Enumerated_device_00 Failed
If you look in properties the devices say
Csrbtport_enumerated_device_00 No Driver Found Windows 10
“The name is already in use either as a service name or a service display name.” This means there are old services using old drivers stopping the new devices from functioning.To fix this you need to remove the old devices/services from the registry.
- Remove the CSR Harmony stack using the Add/Remove Programs in Control Panel. If you have the wrong driver installed (Step 2), but failed to remove it, CSR Harmony will not uninstall and will hang during uninstall.
- Restart the computer.
- If the dongle has been removed, plug it back in and go to Devices and Printers. Findany Bluetooth devices except the dongle and right-click Uninstall and select to delete drivers.
- Go to Device Manager and delete the Generic Bluetooth Radio.
- Get out Registry Editor by pressing Win+R and typing regedit and clicking OK. You will need to grant administrative privileges for this to work.
- Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservices
- Backup the entire tree to a file using the Export command.
- Delete the folders named the following: (they are previous CSR dongle driver remnants, as determined by reading through the CSR Harmony stack .INF files):
- csravrcp
- HFGService
- csr_bthav
- CsrBtPort
- csrduncmdm
- csrhfgcc
- csrhidmini
- csrpan
- csrserial
- csrusb
- csrusbfilter
- While you are there, also look for folders starting with bth that have sub-folders. In the case of Bluetooth Hands-Free Audio, this is the BthAudioHF entry – delete that too.Do not go deleting things randomly – you will mangle something serious. Delete Bth* entries which are named with the problematic device name or contain a driver file name which is used by the CSR provided drivers – in the case of BthAudioHF, it points to the driver with conflicts with HFGService.
- I also had to delete BthAVRCP, getting two of the CsrBtPort_Enumerated_device's to work.
- Reboot computer,
- install CSR Harmony.
- Pair with Blaze/Bluetooth device.
