Prolific USB-to-Serial Comm Port (COM15) Driver

The Prolific USB-to-Serial Comm Port (COM15) driver lets Windows communicate with compatible serial equipment through a Prolific USB-to-serial adapter. It is useful for connecting devices such as industrial controllers, diagnostic tools, and older peripherals that require a serial connection rather than a native USB interface. COM15 is the port number assigned by Windows, not a separate adapter model.

Key Features

• USB-to-serial connectivity: Enables compatible software to exchange data with serial equipment connected through the adapter.
• Configurable communication settings: Provides access to supported serial settings, such as baud rate, parity, and flow control, for matching your connected equipment.
• Windows compatibility: Driver packages are available for Windows 10, 8.1, 7, Vista, and XP, depending on the adapter’s chipset revision and the selected release.
• Device Manager integration: Identifies the adapter as a COM port so you can check its status and select the correct port in your serial application.

How to Install Prolific USB-to-Serial Comm Port (COM15) Driver

1. Identify your adapter and system. Check your Windows version and whether it is 32-bit or 64-bit. If possible, confirm the adapter’s chipset revision or hardware IDs in Device Manager.
2. Choose a compatible package. Before starting your Prolific USB-to-Serial Comm Port (COM15) driver download for Windows, verify that the package supports both your operating system and adapter. Choose a trusted free download from Prolific or the adapter manufacturer.
3. Install the driver. Follow the package instructions, including any requirement to disconnect the adapter first. Run the installer, or use Device Manager’s “Update driver” option to browse to the extracted driver files.
4. Connect and verify. Reconnect the adapter and restart Windows if prompted. Open Device Manager and check “Ports (COM & LPT)” for the Prolific entry without a warning icon. Windows may assign a port number other than COM15.
5. Test your serial connection. Select the assigned COM port in your application and match the communication settings to your equipment. For Windows 10/11 systems, confirm explicit compatibility; Windows 11 support is not established by the operating-system list above.

Keep the driver updated when a compatible release addresses connection problems or system changes. The latest version is not always suitable for older Prolific hardware, so check compatibility before you update and retain a working installer in case you need to revert.
