The installation proved first (thanks Microsoft driver database) very difficult!
Difficult put on the ground, the adapter (never mind USB 2.0 or 3.0) then run the setup CD of the Prom.
All the best! The Bluetooth settings menu, etc. is displayed on the right in the taskbar (CSR Bluetooth).
Listen to music with no problems (coupling with an August EP650). So far so good.
After a while I was a new driver through Windows Update service to download from the Microsoft Update Server
offered. Thought is already fit, ie installed.
Nu but all Bluetooth services were gone (incl. Control Panel devices etc.).
Thought at first it was a failure of the adapter, because this is no longer the green LED flashed regularly.
All over again. Everything as usual, LED flash and the connection to my headphones is also available again.
Like the first time, the update Microsoft offering .......... reinstalled .... and total failure. Nothing works anymore.
Mistakes are a learning well known, so I've hidden the update offer permanently.
In summary, it is to say; Install the CD and re-install in no case any updates!
Thus, the coupling even smartphones from Bq, Wiko and Huawei works with my headset but no problems.
Strong buy recommendation for this well functioning part.
