Before diving into the driver installation, let’s clarify what this cable actually is. The GEV189 is a USB-to-TTL serial adapter. One end has a standard USB-A male connector (plug into your PC). The other end usually has 4 female Dupont wires or a proprietary connector with pins for:
Inside the molded USB plug housing is a small chip—typically the Prolific PL-2303HX or PL-2303TA. Unfortunately, official drivers from Prolific after 2012 deliberately block counterfeit or older chips. Since many GEV189 cables use older or cloned chips, the latest official drivers will reject them on Windows 10.
The GEV189 isn't a special snowflake. It’s a generic USB-to-serial (TTL) programming cable. Inside that chunky plastic blob midway down the wire lives a tiny chip—almost always the Prolific PL2303HX or a clone.
For years, this cable was the universal key to programming two-way radios. On Windows XP and 7, it worked like magic. But Microsoft, in its infinite wisdom, dropped support for older, "unauthorized" serial chips starting with Windows 10 Version 1703 (Creators Update). usb download cable gev189 driver windows 10 new
Do not let Windows automatically search for drivers. It will install the new Microsoft driver, which explicitly blocks older chips.
Instead, download the legacy driver package:
If you search for "GEV189 driver Windows 10 new," you’ll find hundreds of dead ends, shady driver download sites (warning: malware central), and forum posts telling you to "just install the old driver." Before diving into the driver installation, let’s clarify
Here’s the catch: Installing the old driver does work—but Windows 10 will automatically update it to the broken one within hours unless you stop it.
Note: Older PL-2303 HXA/HXB chips are not supported on Windows 10 v1709+. For those, use a PL-2303 TA/TB chip or switch to CH340.
Q: Will this driver work on Windows 11? A: Yes, the same driver version 3.3.2.105 works perfectly on Windows 11 as the driver model is similar to Windows 10. Inside the molded USB plug housing is a
Q: My GEV189 cable has 4 wires – what’s the color code? A: Usually Red = VCC (5V), Black = GND, White = TX, Green = RX. Always verify with a multimeter.
Q: Can I use this cable to unbrick my router/satellite receiver? A: Yes, provided your device has a serial console header (3.3V TTL logic, not RS-232). Never connect VCC unless the device requires external power.
Q: Why does my COM port disappear after reboot? A: The driver might have been overwritten. Repeat the installation and disable automatic driver updates via Group Policy.
