Problem

You want to make sure your Logitech G502 mouse is running the latest firmware to ensure compatibility, performance, and bug fixes—but you’re not sure how to check or update it.

Solution

Firmware updates for the G502 are handled automatically through Logitech G Hub. You can manually check for updates and install them in just a few steps.

Step-by-Step Guide

1. Open Logitech G Hub

2. Access Device Settings

  • Click on the image of your G502 mouse
  • In the top-right corner, click the gear icon ⚙️ (Device Settings)

3. Check for Firmware Updates

  • Inside Device Settings, look for a “Firmware Version” section
  • If an update is available, you’ll see an “Update” button
  • Click Update and wait for the process to complete

The mouse may temporarily disconnect and reconnect during the update—this is normal.

4. Keep the Mouse Plugged In

  • For wired models, ensure the cable is securely connected
  • For wireless models, ensure:
    • The mouse is powered on
    • The receiver is connected
    • The battery is not critically low

Do not power off or unplug the device during the update.

5. Confirm the Update

  • After the update completes, the new firmware version will be displayed in Device Settings
  • Test the mouse to confirm normal operation

Troubleshooting Tips

  • If the update fails or hangs:
    • Quit and reopen G Hub
    • Try a different USB port
    • Reboot your PC and retry
  • Still stuck? Reinstall G Hub:
    • Uninstall → Remove LGHUB folders → Reinstall from Logitech’s website

Notes

  • Firmware updates may improve:
    • Polling rate stability
    • Battery optimization (wireless models)
    • Button responsiveness
    • Lighting control compatibility
  • G Hub checks for updates periodically, but you can manually check any time
