MacOS: The WLN KD-C1 has very little support. The CP2102 driver works natively on macOS. For Prolific, download the Mac driver from Prolific. However, there is almost no native CPS for Mac. You will need to run Windows via Parallels or Bootcamp.
Linux (Ubuntu/Debian):
The kernel includes built-in drivers. Simply plug in the cable, run dmesg -w to see it mount as /dev/ttyUSB0. Then run the Windows CPS via Wine or use the open-source CHIRP radio programming tool (which has experimental support for KD-C1 variants).
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. 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).
Follow these instructions carefully to ensure your KD-C1 is recognized correctly.
The most reliable source is WCH’s official website. Search for "WCH CH340 driver" or use the direct link structure (typically www.wch.cn > Download > CH341SER.EXE). MacOS:

Websites that support radio programming software often host the driver:
For macOS, Prolific provides signed drivers (check their site). For Linux, the kernel often includes the pl2303 module; just plug and play, then use chirp (available via apt or pacman) to program the radio.
If you have recently purchased a WLN KD-C1 (often found as part of an SDR kit, a USB relay board, or a specialized radio accessory), you may have run into a common issue: you plugged it in, and your computer didn't recognize it. However, there is almost no native CPS for Mac
Don't worry—this is standard for devices utilizing specific USB-to-Serial chips. To get your device up and running, you need the correct WLN KD-C1 USB driver.
In this guide, we will walk you through identifying the chip inside your device, downloading the right driver, and installing it on Windows or Linux.
If your cable has the CP2102 chip, you are fortunate. Silicon Labs provides excellent, stable drivers.
