How to Enable COM Ports on Windows 10 or 11 and Use Prolific PL2303 USB to Serial Cable. In this video, you will learn how to add a feature in Windows 10 or 11 and use a USB Device to communicate on a Serial Port.

Here is a step-by-step troubleshooting guide to enable COM ports on Windows 10 or 11 and use a Prolific PL2303 USB to Serial cable:

Step 1: Check if the Prolific PL2303 USB to Serial cable is properly connected to your computer's USB port. If it is not connected properly, unplug it and plug it back in.

Step 2: Verify that the device is recognized by the system. Open the Device Manager by pressing the Windows key + X and selecting "Device Manager" from the menu. Look for "Ports (COM & LPT)" and expand the section to see if the Prolific PL2303 USB to Serial cable is listed. If it is not listed, try connecting the cable to a different USB port on your computer.

Step 3: Check if the correct driver is installed. Right-click on the Prolific PL2303 USB to Serial cable in the Device Manager and select "Properties" from the menu. Click on the "Driver" tab and check the driver version. If the driver is outdated or missing, download the latest driver from the Prolific website and install it.

Step 4: Enable the COM port. Right-click on the Prolific PL2303 USB to Serial cable in the Device Manager and select "Properties" from the menu. Click on the "Port Settings" tab and then click on the "Advanced" button. In the Advanced Settings window, select the COM port number that you want to use and click on "OK". Make sure that the COM port is not already in use by another device.

Step 5: Test the connection. Open a terminal emulator program such as PuTTY or TeraTerm and configure it to use the COM port that you enabled in step 4. Try sending some data through the serial connection and verify that it is received correctly.

If you follow these steps and still cannot get your Prolific PL2303 USB to Serial cable to work properly, you may need to contact the manufacturer for further assistance.
