BRB_SCO_FLUSH_CHANNEL
Profile drivers use the BRB_SCO_FLUSH_CHANNEL request to flush the read and write pipes of the SCO channel. All pending data transfer IRPs will be completed with STATUS_REQUEST_ABORTED. In-progress IRPs will be completed normally, with success or failure depending on whether the Bluetooth driver stack was able to transfer data to or from the remote device.
