cleanflight failed to open serial port windows 10

The error can be caused by hardware issues. Try the solutions and one must work for you. Here you will learn the top solutions to fix the problem. The error could be caused by different issues. Restart your computerįinally, you can try restarting your computer to see if that fixes the issue.If you get Unknown USB Device (Port Reset Failed) error in Device Manager, your USB device most probably won’t be recognized by your PC. The next suggestion would be to use a different USB port – sometimes one USB port is misbehaving for some strange reason. Using a new or even different cable fixed the problem. It would be moody, with it working sometimes and not others. I’ve found that using an older USB cable sometimes refused to let the board connect properly. If it still doesn’t connect… Try using another cable I am not completely sure what the difference between the two is, so perhaps someone can be kind enough to explain it in the comments! 🙂 I’ve found that it works with both “tty” and “cu”. If I click on the menu, I can see other ports, and the one I need to select is “USBModem1421”. You can see in the image below that in my computer, the default selection is “Bluetooth incoming port”, which is incorrect.

To check that it’s working correctly, you can look at the drop down menu in the top right of the configurator and see which COM port the configurator is trying to connect through. Unplug your flight controller from the USB if it was plugged in.Ĭlose Chrome and the configurator, open them up again, plug in your flight controller, and when you click connect, it should now start working fine. Simply install the drivers – it takes less than 2 minutes, and if prompted, restart your computer. The drivers are available for Windows, Linux, and Mac, so you should be covered. The fix for this is fairly easy, you just need to download the Virtual COM port drivers from SiLabs. That’s just the way the chips on the flight controller can be read from and written to. The flight controller talks to your computer through a USB port, but it’s not a direct USB interface – instead, the software must be “tricked” into thinking it’s actually an old fashioned serial COM port. Sometimes, when you connect a board(such as one with Betaflight), the configurator will show you an error that says: To set up a multirotor before you start flying, you have to hook it up to your computer to tweak settings in the flight controller’s configurator, whether it’s Betaflight, Cleanflight, Raceflight, or Kiss(or anything else for that matter).
