Prolific USB-to-Serial Comm Port (COM10) Driver

The Prolific USB-to-Serial Comm Port (COM10) driver lets Windows communicate with compatible serial equipment through a Prolific-based USB-to-serial adapter. It is needed by users connecting devices such as industrial controllers, diagnostic tools, and older peripherals that rely on a serial connection. COM10 is the port number assigned by Windows, not a separate adapter model.

Key Features

• USB-to-serial communication: Provides a virtual COM port that compatible applications can use to exchange data with connected serial equipment.
• Serial connection settings: Allows supported communication parameters, such as baud rate, parity, and flow control, to be configured for the attached device.
• Windows compatibility: Driver packages are available for supported Prolific hardware on Windows 10, 8.1, 7, Vista, and XP; the correct package depends on the adapter’s chipset and operating system.
• Device management: Makes the adapter available in Device Manager so you can check its status, confirm its COM port assignment, and troubleshoot connection problems.

How to Install Prolific USB-to-Serial Comm Port (COM10) Driver

1. Identify your adapter and Windows version. Check whether your system is 32-bit or 64-bit. If necessary, open Device Manager, select the adapter’s Properties, and inspect Hardware Ids under the Details tab to help identify compatible hardware.
2. Choose a compatible package. Before starting a Prolific USB-to-Serial Comm Port (COM10) driver download for Windows, verify that the package supports your chipset and operating system. For Windows 10/11 systems, check compatibility separately: Windows 11 is not included in the supported OS list provided here.
3. Download and install the driver. Use a trusted source for a free download. Run the installer and follow its instructions, including any request to disconnect the adapter. If the package contains only driver files, use Device Manager’s Update driver option and browse to the extracted folder.
4. Reconnect and verify. Restart Windows if prompted, then connect the adapter. Look under Ports (COM & LPT) in Device Manager and confirm that the device appears without a warning icon.
5. Configure your application. Select COM10—or the port currently assigned by Windows—and match the serial settings required by your equipment.

Keep the driver updated when a compatible release addresses connection issues or improves support for your system. The latest version is not always suitable for older Prolific chipsets, so verify hardware compatibility before you update and retain a working installer in case you need to roll back.
