Due to the fact that Windows doesn’t support Bluetooth headset profile (HSP) out of the box, if you want to use a Bluetooth headset with your adapter, you’ll need a little creative workaround to add the headset profile to the default Microsoft stack. Download either of the x86 or x64 compilations of the and extract its contents to a folder. When you try to pair your headset to your computer, Windows will ask for drivers for the headset since it doesn’t find the appropriate headset profile.

Point Windows to the folder where you have extracted the CSR drivers to make it work. Make sure you go into the device in the Bluetooth Devices panel and check off the boxes for unwanted profiles. But first, do you have a BT radio installed?

Well, after a lot of trying I finally gave up and went back to BlueSoleil BT stack. Although, I do not like it but that is what I have to use.

I am thinking about buying a Broadcom chip based BT adapter. Broadcom BT software works very nicely with the Windows 7/Vista BT stack. Anyways, here is what I found on CSR so far Please note that these are all 64-bit drivers as all my systems run 64-bit OSes.

CSR Driver v1.0.0.376 x64 (almost same as Komeil’s): This package contains all the profile drivers I could find and some more. The drivers included here installs nicely for any generic BT hardware. Unfortunately BT Stereo Audio does not work. I got error code 31 in DM. Let me know if you find a fix. CSR Driver x64 v5.0.14: These are the latest drivers I could find.

Unfortunately, these drivers do not load for generic BT devices. Can someone play around with this? Go to for a wealth of csr drivers. Carefull: switching a2dp stereo drivers from pre-4.x.x drivers to post-3.x.x drivers and vice versa requirers erasing the HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet services bthav and HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet services csr_a2dp registry key. I prefer version 2.0.140. 3.0.183 bsod on me, and post-3.x.xx was not stable enough for me, like interupting audio from itunes on dis/reconnection, “disconnected” stereo, etc.
