In this case, the error appeared on a Linux when trying to upload code due to the drivers not being installed and the root permissions. language:bashĪvrdude: ser_open(): can't open device '/dev/ttyUSB0': No such file or directory You may receive an avrdude: ser_open(): can't open device error similar to the output shown below. These drivers are used if you are having issues connecting your flight controller to your PC.

If you installed the drivers for the CH340 on your computer but have issues connecting via serial terminal or uploading code using the Arduino IDE, there may be an issue with your user settings preventing you from using the CH340. Next in the STM32 CubeMX perspective, enable the HSE ( High Speed External) Clock and select Ceramic/Crystal Resonator ( This will depend on your development board. COM Port Not Available Windows, Mac, and Linux

Users seem to be able to eventually get the board recognized by a combination of giving the computer time to finish the install ( close to 20 min), plugging the board back in multiple times, reinstalling the drivers, and/or resetting the computer multiple times ( repeat both steps). Others have had issues where the installation process hangs.īased on the customer experiences, this might be specific to the manufacturer and are usually isolated cases. Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. However, the board cannot be accessed on the Arduino IDE. STM32 USB device - device descriptor request failed. USB Communication Device Class (CDC), or Virtual COM Port, is a standart USB device class supported by any modern Windows without any additional user driver. We have had a few reports on Windows 10 where the driver will automatically install and the board will show up under a new COM port as USB-Serial CH340, but with a different device name. Im working on a very very 'fresh' Win10 installation, so it might be a driver issue, but as stated on STs website the VCP driver preinstalled with Windows 10 should be the preferred one, and in any case ST provides VCP driver only for Windows 7 and Windows 8. But trying to access the device with my application will be aborted by error, it seems the system description still holds the error message.Troubleshooting COM Port is Not Showing Up as CH340 Windows If plugged in again it is possible to read the Windows Device Description by USBTreeView and the device is shown in the display without any error. This error disappears in case of unplug and replug of the device USB connection. The interface problem melts down to a corrupted USB Device Description for the STM-Driver with the windows error message ConfigDescriptor 1 Error : ERROR_CRC. I am the first to use the board in conjunction with an FTDI-Controller and this is where the problems became severe.īy protocoling on both USB-Interfaces with some USB-Sniffer I can say that there is no direct interference on both channels in communication.

64bit and windows 7, to make sure Version 1.5.0 is installed though this one comes with a 1.3.1 in the driver details.Ībout the SW on the controller board, I don't have any idea but it's used in the house with a lot of different set up's working. Yes, did follow the instructions well, I made a deinstall with driver-SW-erase of the previous driver before installing the new driver with adequate attributes, i.e.
