Microsoft BallPoint Serial Mouse Driver

The Microsoft BallPoint Serial Mouse driver helps Windows recognize this legacy Microsoft pointing device and interpret its movement and button input. Because it uses a serial connection rather than USB, successful setup depends on both a working serial port and a driver compatible with your Windows installation.

Key Features

• Serial pointing-device support: Enables communication between the Microsoft BallPoint Serial Mouse and Windows through the appropriate serial interface.
• Movement and button handling: Translates the device’s input into pointer movement and supported mouse-button actions.
• Windows mouse settings integration: Allows pointer behavior to be adjusted through standard Windows mouse controls where supported.
• Legacy hardware setup: Helps keep older input hardware usable on systems with a suitable serial connection and compatible driver support.

How to Install

1. Check compatibility before downloading. Confirm that the driver package specifically lists the Microsoft BallPoint Serial Mouse and your Windows version. For Windows 11, 10, 8, or 7, also check whether the package matches your system architecture. A legacy driver should not be assumed to support every listed operating system.

1. Prepare the serial connection. Shut down the computer before connecting the mouse to its serial port, then restart. If you use a USB-to-serial adapter, install the adapter’s driver first and confirm that it supports serial pointing devices; not every adapter will work with this mouse.

1. Download and extract the driver. Save the compatible package to an accessible folder. Extract any compressed files, and review included installation instructions before proceeding.

1. Install using the provided method. Run the installer if one is included. For a manual installation, open Device Manager, locate the relevant detected device, select Update driver, and browse to the extracted folder. Do not force an unrelated driver or bypass Windows security warnings.

1. Restart and test the mouse. Check pointer movement and button response, then adjust available mouse settings. If the device remains unresponsive, verify the serial connection and COM-port status before reinstalling. Keep another working input device available during troubleshooting.
