Can't find the serial port? Can't connect to Configurator (wrong driver installed)?

Under normal circumstances, you can find the device corresponding to FC in Port (COM&LPT).

If your device is not found in the COM column, and the serial port fails to be opened in the Betaflight（INAV） configurator, it is likely that the wrong driver is installed.

Step 1:
Please open the computer management of the computer, enter the device manager, and find the device corresponding to FC (probably called Betaflight stm32f7x2).

You can also plug and unplug FC, and the extra device that appears is the device corresponding to FC.

Step 2:

1. Right-click to select the FC device, and select Update Driver.

2. Click: Browse my computer for drivers、

3. Select: Let me pick from a list of available drivers on my computer

Step 3:

Select update as USB Serial Device.

If the FC is found, but it shows an unknown device, it means the FC is bricked, please enter the DFU mode to reflash the firmware.

If the FC device cannot be found, please try to replace the cable, or enter the DFU mode to reflash the firmware.
