 Currently there is no support for virtual com port functionality on the CC3D which means that cleanflight

+does not currently use the USB socket at all. So the communication with the board is achieved through a USB-UART adaptater connected to the Main port.
 
 The board cannot currently be used for hexacopters/octocopters.
