Logitech Gaming USB G3 (MX518) Optical Mouse Driver

The Logitech Gaming USB G3 (MX518) Optical Mouse driver helps Windows recognize the mouse and handle its USB input for pointer movement, clicks, and scrolling. When paired with compatible Logitech software, it may also provide access to button assignments and sensitivity settings beyond basic mouse operation.

Key Features

• USB mouse recognition: Supports communication between the Logitech mouse and Windows so standard pointing and clicking functions work correctly.
• Everyday input controls: Enables core mouse functions, including cursor movement, primary button clicks, and scroll-wheel input.
• Optional gaming customization: Compatible Logitech software may offer programmable button actions and pointer sensitivity adjustments, depending on the exact hardware model and software version.
• Windows setup support: Helps you select an appropriate driver for your system. For Windows 11, 10, 8, or 7, check the individual package’s compatibility information before downloading; older Logitech utilities may not support every version.

How to Install

1. Confirm your mouse model and Windows version. Check the label on the underside of the mouse and open Windows system information to identify your operating system and whether it is 32-bit or 64-bit. Because G3 and MX518 are distinct model names, verify the hardware ID in Device Manager if the download listing combines them.
2. Choose a matching driver package. Select a download that explicitly supports your hardware and Windows version. Avoid installing software intended for a different Logitech mouse solely because its name looks similar.
3. Connect the mouse directly to your PC. Plug it into an available USB port and allow Windows to finish detecting it. Basic mouse functions may already work with the built-in Windows USB mouse driver.
4. Install the downloaded software if needed. Run the installer and follow its prompts. If the package contains driver files without an installer, use Device Manager’s Update driver option and browse to the extracted folder.
5. Restart if prompted and test the controls. Check pointer movement, scrolling, and button response. If compatible Logitech configuration software is available, open it to adjust supported settings.

If installation fails or the mouse stops responding, try another USB port and confirm that the package matches the device. For basic use, the Windows-provided driver may be sufficient without additional Logitech software.
