Hw-417-v1.2 Driver |best| -

Modern Windows drivers from FTDI may intentionally "brick" or disable these non-genuine chips by changing their USB Product ID (PID) to "0000". If you have a clone board, users often need to use older driver versions (such as v2.8.3) to maintain functionality, or use the device on Linux or macOS , where driver-level "bricking" is less common. Common Applications Drivers - FTDI

You should see "USB Serial Port (COMx)" or "FTDI FT232R USB UART."

If your computer throws errors or fails to recognize the HW-417-V1.2 board, use these steps to resolve the conflict. Error: "Device Descriptor Request Failed" (Code 43)

Therefore, when you are looking for an "HW-417 driver," you are actually looking for the . hw-417-v1.2 driver

Unplug the USB adapter and plug it back in. Windows will finalize the driver setup at this point. A notification may appear saying "Device is ready."
