The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver.
The CP210x Manufacturing DLL and Runtime DLL have been updated and must be used with v 6.0 and later of the CP210x Windows VCP Driver. Application Note Software downloads affected are AN144SW.zip, AN205SW.zip and AN223SW.zip. If you are using a 5.x driver and need support you can download Legacy OS Software.
Important note regarding Windows 7 and Vista: The driver MUST be installed \"as Administrator\" Right-click the downloaded EXE file and choose Run as administrator
If for some reason the above driver does not work, try one of the following: Download for Windows 7/Vista/XP (32-bit and 64-bit - Alternate driver) Download for Windows XP, 2000, 98/ME (32-bit only)

In this tutorial, we'll show you how to install CH340 drivers on multiple operating systems if you need. The driver should automatically install on most operating systems. However, there is a wide range of operating systems out there. You may need to install drivers the first time you connect the chip to your computer's USB port or when there are operating system updates.
These operating systems have the CDC drivers pre-installed, which means you shouldn't need to install any extra software. However, there are a wide range of operating systems out there, so if you run into driver problems, you can get the archived drivers linked below:
You can also verify if the USB-to-serial converter is working by doing a serial loop back test or echo test. If you are using the breakout board, you can add a jumper between the Tx and Rx to try and echo a character in a terminal program. For more information, try checking out the Hardware Test for the serial basic hookup guide.
If you have found the file in the path, you will need to run each of the following commands in the CLI/Terminal to remove old CH340 drivers. In this case, there was only the usbserial.kext file but it does not hurt to run both commands. Make sure to have administrative privileges to ensure that the drivers are removed.
Check if the old drivers were removed in the paths by using the ls command with your respective OS version. You will notice that the *.kext file is removed from the respective paths. In this case, the usbserial.kext was removed from Mac OSX High Sierra.
There are some reported cases of serial communication failure when using the factory drivers in Linux. If you encounter this problem, you can try installing patched drivers as explained in this forum post. Here are the steps (to run in the command line):
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. However, the board cannot be accessed on the Arduino IDE. Others have had issues where the installation process hangs.
Based on the customer experiences, this might be specific to the manufacturer and are usually isolated cases. 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).
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. You may receive an avrdude: ser_open(): can't open device error similar to the output shown below.
If you are uploading to certain boards like the Apollo3 on the Artemis development boards with fast baud rates, there are some platforms (Linux flavors) where the standard CH340 USB to serial drivers don't operate well at speeds higher than 115200. So if you run into upload problems, consider reducing the upload speed. For more information about upload issues, see this forum post and consider upgrading with these drivers for Mac OSX or these for Linux.
USB-to-serial converters like the CH340 are great for uploading code to a microcontroller or viewing data from a GPS on a serial terminal. Check out these tutorials to dive even deeper into the world of microcontrollers or send serial data to your computer with a GPS!
Windows standard driver will be loaded if you inserted the USB device in the USB port of the PC with Windows 10/Windows 11 which does not install Active USB-COM Port Driver.The USB device does not support the operation with the Windows standard driver.Please use it after installing Active USB-COM Port Driver by all means.
Below is the latest download from DisplayLink for Ubuntu distributions. This release has been prepared to be compatible with Ubuntu. Please see our support page for information on how to install this driver on Ubuntu.
Note: This is a reference driver for supported DisplayLink USB graphics device that is incorporated in your dock, adapter or monitor. However, please note that your original equipment manufacturer (OEM) provides drivers for your specific monitor, dock or adapter on their website, etc. DisplayLink recommends that you check with your OEM about recommended driver updates for your monitor, dock or adapter. An OEM may not provide technical support for issues that arise from the use of this driver.
DisplayLink has not created drivers for other packages, however the Ubuntu driver contains an open source component which is designed to be modified to enable the Ubuntu driver to be repackaged for any other Linux distro by the user community. Details on how the Ubuntu driver package can be unpacked and modified for other distros is covered in this article.
This package contains both Windows and Linux USB drivers for the Aardvark I2C/SPI Host Adapter, Beagle Analyzers, Cheetah SPI Host Adapter, Komodo CAN Duo Interface, and the USB Power Delivery Analyzer.
