My G502 isn’t being detected by G Hub—what should I do?
Applies to: Logitech G502 Hero / G502 Lightspeed / G502 X / G502 X Plus
Last updated: May 2025
Problem
You’ve connected your Logitech G502 mouse, but it doesn’t show up in Logitech G Hub, or the software says “No Devices Detected.” This prevents you from customizing DPI, buttons, lighting, and profiles.
Solution
This issue is typically caused by a USB detection problem, G Hub installation glitch, outdated firmware, or driver conflicts. Follow these steps to fix it.
Step-by-Step Troubleshooting Guide
1. Restart G Hub and Your PC
- Right-click the G Hub icon in the system tray > Quit
- Reopen G Hub as Administrator (right-click > Run as Administrator)
- If the mouse still doesn’t show, restart your PC
2. Check USB Connection
For Wired G502:
- Plug into a different USB-A port (direct on motherboard preferred)
- Avoid USB hubs, docking stations, or front panel ports
For Wireless G502:
- Ensure the receiver is plugged in
- Turn on the mouse using the switch on the bottom
- Use the included USB extender to reduce interference
3. Check Device Manager
- Press
Win + X> Device Manager - Look for the mouse under:
- Mice and other pointing devices
- Universal Serial Bus controllers
- If marked with a warning (!) or unknown device:
- Right-click > Uninstall > Reboot
- Reconnect the mouse
4. Update or Reinstall G Hub
- Uninstall Logitech G Hub:
Settings > Apps > Logitech G Hub > Uninstall
- Delete leftover folders:
C:\Program Files\LGHUBC:\Users\<YourName>\AppData\Local\LGHUB
- Restart your PC
- Download the latest version: https://www.logitechg.com/ghub
- Reinstall and launch
5. Check for Firmware Updates (If Detected Later)
Once the mouse appears:
- Click the gear icon ⚙️
- Check for a firmware update
- Apply and reboot if necessary
6. Use Onboard Memory as Fallback
If G Hub won’t detect the device but it works otherwise:
- Switch the mouse to Onboard Memory Mode (hardware profiles still function)
- Use default DPI, lighting, and button mappings until G Hub is restored
Advanced Fix (Wireless G502)
If the receiver is not pairing:
- In G Hub, click Add a Device
- Hold down DPI button + Left Click + Right Click for 5–10 seconds to enter pairing mode (model dependent)
- Try reconnecting
Notes
- G Hub requires Windows 10 or macOS 11+ to function properly
- Some antivirus or security tools may block G Hub—try disabling them temporarily
- For enterprise PCs, make sure you’re not restricted by group policies or admin controls
