PS 2 Port Input Device Driver

The PS 2 Port Input Device driver helps Windows communicate with a compatible keyboard, mouse, or other input device connected through a PS/2 port. If your device is unrecognized, stops responding, or shows a warning in Device Manager, checking the driver is a useful troubleshooting step. This page is intended for users looking for a compatible driver for Windows 11, 10, 8, or 7.

Key Features

• Input device communication: Enables Windows to receive keystrokes, pointer movement, or other supported input through the PS/2 interface.
• Device recognition: Helps Windows identify and configure compatible input hardware using the appropriate driver.
• System integration: Works with Windows input services so supported devices can function in applications and system menus.
• Compatibility-focused setup: Using a driver matched to your hardware and Windows version can help resolve driver-related detection or operation problems.

How to Install PS 2 Port Input Device Driver

1. Check your device and Windows version. Open Device Manager and locate the input device, which may appear under Keyboards, Mice and other pointing devices, or Other devices. Review its properties and hardware IDs if the device name is unclear.

1. Find a compatible package. Before starting a PS 2 Port Input Device driver download for Windows, confirm that the package supports your hardware, operating system, and system architecture. Choose the latest version approved for your device, rather than assuming every newer package is compatible.

1. Use a trusted source. Check Windows Update or support resources from the manufacturer for a free download, where available. Many PS/2 keyboards and mice use drivers included with Windows, so a separate download may not be necessary—even on Windows 10/11.

1. Install the driver. If you downloaded a compatible installer, follow its instructions. For an extracted driver package, open Device Manager, select Update driver for the device, and choose Browse my computer for drivers to locate the files.

1. Restart and test. Restart Windows if prompted, then check that the device responds correctly. If reconnecting a PS/2 device is necessary, shut down the computer before unplugging or attaching it.

Keep the driver updated through Windows Update or a verified source from the manufacturer. An update may address compatibility issues, but a working input device does not always need a separate driver replacement. If problems begin after an update, check whether Device Manager offers Roll Back Driver.

Common Issues and Fixes

• Device not detected: PS/2 is not hot-pluggable. Shut down, reseat the keyboard/mouse in the correct purple/green port, and reboot. Check BIOS/UEFI for a disabled PS/2 or legacy input setting.
• Install fails: Windows often already provides the PS/2 driver. Confirm the installer matches your Windows version and architecture, run it as administrator, or update via Device Manager > Update driver > Browse.
• Version conflicts: Remove old PS/2 driver packages in Device Manager, including “Delete the driver software,” then reboot and reinstall the vendor package. Avoid installing multiple PS/2 driver versions at once.
