Check Device Manager: Plug in your cable, right-click the Start button, and select Device Manager. Look under Ports (COM & LPT).

Identify Missing Drivers: If you see "USB Serial Controller" with a yellow warning icon under "Other Devices," you need to manually install the chipset driver.

Clean Reinstall: If the cable is unrecognized, uninstall the existing faulty driver from the Device Manager before running a fresh installer from FTDI or Silicon Labs.

Terminal Software: Once the driver is verified, use software like PuTTY or Tera Term to connect to your hardware's console port. Related Products USB Serial Port Driver for console cable - Problem Solved Windows may be powering down your AWM 20251

| Problem | Solution | |---------|----------| | Code 10 (Device cannot start) | Driver rejecting counterfeit chip → use legacy v3.3.2.102 or buy a genuine cable. | | Driver installs but no COM port | Try different USB port, reboot, or disable driver signature enforcement. | | macOS not recognizing | Install PL2303.kext from Prolific’s macOS driver (SIP may need adjustment). | | Linux – lsusb shows device but no /dev/ttyUSB* | Run sudo modprobe pl2303, then check dmesg. |

You’ve installed the old driver. It works. But Windows Update is lurking in the shadows, waiting to "upgrade" you back to the broken version.
