How to Install Prolific USB-to-Serial Comm Port Driver for Windows XP

If you have a device that uses a Prolific USB-to-Serial Comm Port (such as a GPS receiver, a serial console cable, or a programming cable), you may need to install a driver for it to work properly on Windows XP. The driver is available from the Prolific website[^1^] or from some device manufacturers[^2^]. However, some users may encounter a \"Code 10\" error message when trying to use the device, indicating that the driver is not compatible with the operating system. This article will show you how to fix this problem and install the correct driver for your device.

Step 1: Uninstall any existing Prolific drivers

Before installing the new driver, you need to uninstall any previous versions of the Prolific driver that may be present on your system. To do this, follow these steps:

Unplug any Prolific USB-to-Serial Comm Port devices from your computer.

Go to Control Panel > System > Hardware tab > Device Manager.

Scroll down to Ports (Com & LPT) and expand the category.

Right-click on any Prolific USB-to-Serial Comm Port (COM#) and select Uninstall.

Repeat this for any other Prolific devices in the list.

Restart your computer.

Step 2: Download and install the latest Prolific driver

The latest version of the Prolific driver for Windows XP is 3.3.2.102, dated 09/24/08[^3^]. You can download it from the link below:

Prolific PL-2303 Driver Setup Installer for Windows XP

After downloading the file, run it and follow the instructions to install the driver. You may need to accept a security warning or agree to a license agreement during the installation process.

Step 3: Verify that the driver is working

After installing the driver, you can plug in your Prolific USB-to-Serial Comm Port device and check if it is working correctly. To do this, follow these steps:

Go to Control Panel > System > Hardware tab > Device Manager.

Scroll down to Ports (Com & LPT) and expand the category.

Double-click on Prolific USB-to-Serial Comm Port (COM#).

In the Properties window, click on Driver.

The Driver Version should say 3.3.2.102 dated 09/24/08. If not, then the correct driver is not installed.

The Device Status should say \"This device is working properly.\" If not, then there may be a problem with your device or your USB port.

If everything looks fine, you can close the Device Manager and use your device as normal. You may need to configure the COM port number and other settings for your specific application or software.
