In the world of affordable, compact two-way radios, the WLN KD-C1 (often referred to as the "Mini KD-C1" or "Retevis RT22 clone") has carved out a significant niche. Praised for its tiny size, extended battery life, and surprisingly powerful output, this little UHF radio is a favorite among security teams, event staff, warehouse crews, and outdoor enthusiasts.
However, to unlock the full potential of the KD-C1—such as programming frequencies, adjusting squelch levels, activating hidden features, or cloning configurations to multiple radios—you need one critical piece of software and hardware bridge: The WLN KD-C1 USB Driver.
If you are staring at a "Device Not Recognized" error or struggling to connect your radio to your PC, you've come to the right place. This comprehensive guide will cover everything you need to know about the WLN KD-C1 USB driver, including where to download it, how to install it correctly, common error fixes, and how to use it with popular programming software (CPS).
The WLN KD-C1 USB driver is a small piece of software with a big impact. Without it, your $20 mini radio is stuck with factory default frequencies. With it, you transform the KD-C1 into a powerful, customizable communication tool.
Most connection problems are not due to a broken radio or cable, but rather a driver conflict with Windows 10/11's strict driver signing policies. By following the identification and installation steps outlined above, you should be able to read and write to your KD-C1 in under 10 minutes.
Final Pro Tip: Once you have the driver working, buy a second programming cable immediately. They are cheap, and losing a working driver setup is frustrating when the cable physically breaks. Label the working cable "Good Prolific" and keep the driver installer in a folder on your desktop.
Now, go program your radios—just ensure you stay within your country’s legal amateur or business radio bands.

The WLN KD-C1 is a popular budget handheld radio, but users often face confusion regarding its "USB" port. Crucially, the mini-USB port on the side of the radio is only for charging; it cannot be used to program the device or communicate with a PC. Programming Setup & Drivers
To program the WLN KD-C1, you must use a standard Kenwood/Baofeng 2-pin K-type USB programming cable plugged into the microphone/earpiece jack.
USB Drivers: The driver you need depends on the chipset inside your programming cable:
Prolific Chip: Most common in budget cables. Windows 10/11 users often require specific older versions of the Prolific driver to bypass "Code 10" errors caused by counterfeit chips. wln kd-c1 usb driver
CH340/CH341 Chip: Found in many "no-name" cables. You can download the CH341SER driver from sites like Cape Avionics or the manufacturer's site.
FTDI Chip: Generally the most reliable and "plug-and-play" on modern Windows systems. Essential Software Options
Once your cable is recognized by Windows as a COM port, you can use several software options to manage your 16 channels: Superb Budget Radio - WLN KD-C1 - Range Test

Some common issues that may arise with the driver include: In the world of affordable, compact two-way radios,
To program a WLN KD-C1 radio, you must use a specialized programming cable rather than the built-in mini-USB port. While the radio has a USB port, it is strictly for charging only and will not allow the device to be recognized by a computer for data transfer. Essential Hardware To connect the radio to your PC, you need:
K-Type (Kenwood/Baofeng) Programming Cable: This cable features a two-prong (3.5mm and 2.5mm) connector that plugs into the audio sockets of the radio.
Compatible USB Chip: Cables with a genuine FTDI chip are generally the most reliable as they are more likely to have "plug-and-play" driver support on modern Windows versions. Driver and Software Requirements How To Programme A WLN KD-C1 In Chirp
The WLN KD-C1 USB Driver is a small but critical component for any owner wishing to move beyond basic keypad programming. With the correct driver installed, your PC and radio will communicate flawlessly, allowing you to manage frequencies, backups, and settings with ease. If you encounter the dreaded “Code 10” error, remember: it’s almost always a driver signature issue solvable by installing the latest official Prolific driver and avoiding automatic Windows updates for that device.
Disclaimer: Always ensure you have the legal right to transmit on the frequencies you program. The WLN KD-C1 is often used on amateur radio bands and requires a license in many jurisdictions.
Getting your WLN KD-C1 radio talking to your computer can be a bit of a hurdle, mainly because the radio's built-in USB port is typically for charging only. To program the device, you need a dedicated "K-type" USB programming cable (the same used for Baofeng or Kenwood radios) which contains the serial-to-USB chip that requires a specific driver. Identifying Your Chipset
Before downloading any files, you need to know which chip is inside your programming cable. Most cheap cables use one of two chips:
CH340 (QinHeng): Often the most reliable for modern Windows 10 and 11 systems because it is "plug-and-play" or has official, signed drivers that don't block clone chips.
PL2303 (Prolific): Extremely common but prone to "Error Code 10" on newer Windows versions if the cable contains a counterfeit chip. Where to Download WLN KD-C1 Drivers
Depending on your cable, use the following sources for the official drivers:
For CH340 Cables: Use the CH341SER driver from Cape Avionics. Where to find the WLN KD-C1 USB driver
For PL2303 Cables: You may need an older, specific version (like v1.5.0) to bypass "clone" detection on Windows 10/11.
All-in-One Kits: Sites like RT Systems provide proprietary cables and drivers that are guaranteed to work without manual driver hunting. Step-by-Step Installation Guide
Do Not Plug in the Cable Yet: Install the driver software first to prevent Windows from automatically installing a generic (and often non-working) version.
Run the Installer: Open the .exe file for your specific chip (CH340 or PL2303) and follow the prompts.
Connect the Cable: Plug the USB end into your PC. Open Device Manager (Windows + X > Device Manager) and look under Ports (COM & LPT).
If you see "USB-Serial CH340 (COMx)" with no warning icons, you are ready.
If you see "Prolific USB-to-Serial" with a yellow triangle/Error Code 10, you must manually "Roll Back" or update the driver to an older version.
Configure the Software: Open your programming software (such as the native WLN KD-C1 Setup or CHIRP) and ensure the COM port matches the one assigned in Device Manager. Chirp not working with WLN KD-C1 and CH340 cable?
Before downloading a file blindly, it is important to know which driver your specific version of the KD-C1 needs. Most of these devices use one of two popular chips:
How to check: If you can safely open the casing of the KD-C1, look at the largest black chip on the circuit board. It will likely be printed with "CH340G" or "CP2102".
Some older unsigned drivers trigger false positives.
