Hi Hilda,

> The MSFT extension has a HCI_VS_MSFT_Read_Supported_Features command. The AOSP extension has a read capability cmd too.

> If commands did not support, the controller should feedback event status as Unknown HCI Command (0x01).

I am not doing trial-and-error programming here. I rather better disable any extensions for Realtek devices altogether.

Regards

Marcel
