Many months ago if you ever had any issues with connecting your flight controller to cleanflight/betaflight or any other variation the defacto suggestion would be to first install the suggested drivers for that flight controller and then use the Zadig Driver tool to reinstall the WinUSB drivers which solved 99% of issues.
Use ImpulseRC Driver Fixer Tool
However now there is an easier way thanks to the impulseRC driver fixer tool!
Essentially what this tool does is when your board is connected it can detect which VCP drivers it needs and will install them for you automatically! Nice and simple.
Last resort, select the driver manually
However if that still does not work when it comes to flashing firmware in DFU mode, the last solution is to simply select the correct driver yourself via windows device manager with your flight controller connected in bootloader mode.
Simply select the STM32 Bootloader device within the device manager, right click and select update driver software and follow the images below
That should solve any driver issues but if you still have any questions/problem let me know so we can try figure it out and add it to the guide
