Linux driver for USB to serial port, supports CH340 and CH341, supports 32/64-bit operating systems.ĬH341 datasheet, USB bus converter chip with multiple communication interfaces, such as USB to serial port/parallel port/printer port/I2C interface etc. It should now be listed under the /dev directory. sudo kextload /Library/Extensions/usbserial.kext.Instead of rebooting, you can force quit Installer after it completes.Double-click on the CH34x_Install_V1.3.pkg file and install (no need to reboot).sudo rm -rf /Library/Extensions/usbserial.kext.sudo rm -rf /System/Library/Extensions/usb.kext.Remove the old driver by issuing one of the following commands (depending on your installation):.sudo kext unload /System/Library/Extensions/usb.kext.sudo kext unload /Library/Extensions/usbserial.kext.(MAC OS 32/64bit) for MacOS Sierra/High Sierra This driver is for MacOS Sierra/High Sierra. Do not install the drivers for the Mojave, because it seems that the latest versions are equipped with the built CH340/CH341 support. If the device is not recognized, download the Linux CH340/CH341 driver. The drivers are integrated into different Linux distributions. Once the unzip of the package has been executed, it is possible to proceed with the update of the driver for the device CH340/CH341 and equivalent (download driver only for your OS):ĭrivers in the Windows OS are missing, you need to download and install them. The driver must be downloaded from the official (Chinese) website. No panic, driver installation is very easy! The lack of this driver does not allow you to communicate with the hardware platforms and to use the Arduino development software. Many operating systems do not recognize these chip natively because they lack the drivers and consequently we have an error due to lack of drivers. The CH340/CH341 chip is used by a number of Arduino compatible cards to provide USB connectivity.
