Remarks
This request initiates the process to disconnect the Service Level Connection and ends without waiting for the disconnection to complete. Connection status can be determined using IOCTL_BTHHFP_DEVICE_GET_CONNECTION_STATUS_UPDATE.
The audio driver sends this request from its handler for the KSPROPERTY_ONESHOT_DISCONNECT KS property.
