We must have been using an old example (CDCstandalone) as the latest STM32Cube FW examples already had those bytes set to 0x02. Reconnecting the device at any point, Betaflight asked that the board be reflashed.Īttempts to reinstall en.stsw-stm32102.zip / CP210x_Windows_Drivers.zip and use Zadig have had no effect. I eventually found that changing bDeviceClass and bDeviceSubClass in usbddesc.c to 0x02 will let the Native Windows 10 driver see the device as a COM port. Past this point Betaflight will not allow me to connect to the virtual device and says “Failed to open serial port”. Load in and install the firmware to the F3FC from Betaflight(v3.2.1) “triflight_0.7_Beta2_RCEXPLORERF3.hex” after which the Bootloader drops off and becomes the “STM32 Virtual Com Port”. Je possède actuellement une carte de vol Matek f-405, pour la paramétrer sur Betaflight je dois donc installer le driver STM32 VCP, cependant il nest pas disponible sur Windows 10, je nai jamais monté de drone auparavant et je ne my connais pas très bien en informatique. Insert the USB cable to the F3FC board (boot button held), the “STM32 Bootloader” shows in the device manager and lights are shown on F3FC board. Tried reinstalling all drivers but yet dice… I used the two batch files for drivers but WIN10 does not recognize the stm32. Not sure what I can do as this issue persists on both computers. However recently even this is failing to connect.

Now unplug the FC and reboot your computer. Be aware that I was able to get it to work once on my wife’s laptop. Virtual COM port driver installation package for Windows® operating systems: 98SE, 2000, XP, Vista®, 7, and 8. With your FC connected to the computer in bootloader/DFU mode, go to Device Manager, find Guillemot STM DFU Device, right click it and Uninstall it, make sure to check uninstall driver. Zadig driver loaded and still after the F3FC firmware update, I’m unable to load into the Betaflight configuration screen. Connecting to the tricopter via Betaflight is a constant issue. I see multiple people having this problem but not seen an answer why or a solution: The Virtual COM Port driver (1.4) is not working for Windows 10 users. Here’s how you can easily create virtual COM ports on a Windows 10 PC using Virtual Serial Port Driver: 1 Download the software and install it on your machine.
