Three possibilities:
Most modern KA301 converters use the WCH (Nanjing Qinheng Microelectronics) CH340G chip. This driver is digitally signed and works perfectly on Windows 11, 10, 8, 7, and even Linux/macOS.
Because "KA301" is often a generic model name used by several Chinese manufacturers, simply searching for "KA301 driver" can yield mixed or unsafe results. The most reliable way to find the driver is to identify the chipset.

Comprehensive Guide: Universal Converter KA301 Driver Download and Installation
If you’ve recently purchased or unearthed a KA301 Universal Converter (often used for USB-to-Serial, USB-to-RS232, or similar data communication tasks), you likely know that the hardware is only half the battle. Without the correct driver, your computer will simply label it as an "Unknown Device."
This guide provides everything you need to find, download, and install the KA301 driver to get your hardware up and running. What is the KA301 Universal Converter?
The KA301 is a versatile interface adapter designed to bridge the gap between modern USB ports and legacy peripheral devices. It is commonly used for: Programming PLCs and industrial equipment. Connecting older digital cameras or GPS units. Interfacing with networking hardware via console ports. DIY electronics projects (Arduino/Microcontrollers). Where to Download the KA301 Driver
The KA301 typically uses a common communication chipset. Depending on your version, it likely utilizes a PL2303 (Prolific) or CH340 (WCH) chipset. 1. Official Manufacturer Sources universal converter ka301 driver download
The safest way to download the driver is through the official website of the chipset manufacturer.
For Prolific Chipsets: Visit the Prolific Official Website and look for the "PL2303 USB to Serial" driver.
For CH340 Chipsets: Visit the WCH Official Website and search for the "CH341SER" executable. 2. Third-Party Driver Archives
If you no longer have the mini-CD that came with the device, many reputable hardware driver databases host the specific KA301.zip or KA301_Setup.exe files. Always ensure you scan these files with antivirus software before running them. How to Install the KA301 Driver (Step-by-Step)
Follow these steps to ensure a clean installation on Windows 10 or 11:
Disconnect the Device: Unplug the KA301 converter from your USB port before starting the installation.
Run the Installer: Double-click the downloaded .exe file (e.g., PL2303_Prolific_DriverInstaller.exe). Follow the on-screen prompts and click "Finish."
Connect the KA301: Plug the converter into a functional USB port. Verify via Device Manager: Right-click the Start button and select Device Manager. Expand the Ports (COM & LPT) section.
You should see "Prolific USB-to-Serial Comm Port" or "USB-SERIAL CH340" followed by a COM port number (e.g., COM3). Troubleshooting Common KA301 Issues "Device Cannot Start (Code 10)"
This is the most common error with KA301 converters. It usually happens if Windows automatically installs a newer driver version that isn't compatible with older hardware revisions.
Fix: Use the "Roll Back Driver" feature in Device Manager or manually select an older driver version (e.g., version 3.3.2 for Prolific). Driver Not Found If Windows doesn't see the driver after installation:
Try a different USB port (preferably a USB 2.0 port if you are using 3.0).
Disable your firewall temporarily during the installation process. Identifying Your COM Port
If your software (like PuTTY or a PLC loader) asks for a port, always check Device Manager. If the KA301 is listed as COM4, you must set your software to COM4 with a matching baud rate (usually 9600).
The KA301 Universal Converter remains a reliable tool for serial communication. By ensuring you have the correct chipset driver—whether it’s Prolific or WCH—you can extend the life of your legacy hardware.
I understand you're looking for a driver for the Universal Converter KA301. However, I need to give you an important heads-up:
Do not go to "driver-finder-website-dot-com". Those files contain malware 80% of the time.
The only safe source for the KA301 utility is the chip manufacturer: C-Media. Three possibilities: Most modern KA301 converters use the
The KA301 almost universally uses the C-Media CM108 or CM6206 chip.
How to download safely:
⚠️ Note: There is no official "KA301.com" website. The manufacturer is a generic OEM. Do not trust popups claiming "KA301_Driver_2024.exe".
For SATA/IDE to USB adapters like the KA301, try:
You can find these on Station-Drivers.com (trusted source for chipset drivers).
The Universal Converter KA301 is a robust tool for industrial communications, but it requires the right software bridge to function. Do not rely on random file-hosting sites; identify the internal chipset (likely Prolific or Silicon Labs) and download the driver directly from the chipset manufacturer for the safest, most stable connection.
The Universal Converter KA301 is a multi-function industrial device that converts RS-232, RS-422, RS-485, or TTL signals to a USB interface. It is primarily manufactured by companies like TAIE and Taiwan Instrument & Control (FA-TAIE). Driver Download & Installation
Because this device functions as a USB-to-UART (Serial) bridge, it typically relies on standard third-party controller drivers, most commonly the CH341 or FTDI series.
Official Product Page (TAIE): You can find product documentation and potential driver links on the FA-TAIE KA301 Product Page.
WCH (CH341) Drivers: Most industrial converters of this type use the CH340/CH341 chipset. You can download the latest CH341SER.EXE (Windows) directly from Nanjing Qinheng Microelectronics. Manual Installation:
Download the driver file (e.g., CH341SER.EXE or CDM21228_Setup.exe).
Run the setup utility before plugging in the KA301 converter.
Once the installation is complete, connect the KA301 to your PC's USB port.
Verify the connection in Device Manager under Ports (COM & LPT) to identify which COM port has been assigned to the device. Key Features
Versatility: Supports 4 types of serial communication (RS-232/422/485/TTL).
Bus Powered: Uses DC power directly from the USB port, requiring no external power supply.
