Logitech G Hub not detecting G502 Hero mouse fix

Fix: Logitech G Hub Not Detecting G502 Hero Mouse

You plugged in your Logitech G502 Hero, but G Hub is stuck on the frustrating "Connect your Logitech G Gear" or "No Devices Detected" screen.

To fix G Hub not detecting your G502 Hero, you must first close all hidden G Hub background processes using the Task Manager. Then, open the Windows Device Manager, locate the mouse under "Human Interface Devices," and completely uninstall the device. Unplug the G502, plug it back into a different USB port, and relaunch G Hub as an Administrator to force a fresh driver installation.

If that quick reset didn't work, here are the advanced methods to bypass the software glitch.

Method 1: Kill the Hidden G Hub Agents

Closing G Hub by clicking the "X" does not actually close the software. The background updater often freezes, preventing it from scanning USB ports.

1. Press Ctrl + Shift + Esc to open the Task Manager.

2. Look for three specific processes:

   • LGHUB

   • LGHUB Agent

   • LGHUB Updater

3. Right-click each of these and select End Task.

4. Right-click your Logitech G Hub desktop shortcut and select Run as Administrator. In 90% of cases, your G502 Hero will immediately appear.

Method 2: The Device Manager Driver Wipe

Sometimes, Windows aggressively overrides Logitech's software with generic Microsoft drivers. Having a perfectly tuned mouse is crucial for high-refresh-rate gaming, but it won't help if your PC architecture is causing micro-stutters. If you are running an older CPU and experiencing frame drops even after fixing your mouse, you can check our recent benchmarks to see if an RTX 4060 will bottleneck a Ryzen 5 3600 at 1080p.

1. Press Windows Key + X and select Device Manager.

2. Expand the Mice and other pointing devices and the Human Interface Devices dropdowns.

3. Look for "Logitech USB Input Device" or "HID-Compliant Mouse" (if you unplug the G502 and the listing disappears, you found the right one).

4. Right-click it and select Uninstall Device.

5. Unplug the G502 Hero from your PC.

6. Restart your computer. Once you are back on the desktop, plug the mouse directly into a USB port on the back of your motherboard (avoid using front panel case hubs or USB splitters).

Method 3: Reinstall Using the Official Logitech Tool

If your G Hub installation is corrupted, it will never detect older mice. You must download a fresh copy directly from the Logitech G Official Support page.

Do not just delete the folder. Go to Windows Settings > Apps, find Logitech G Hub, and uninstall it properly. Once removed, download the latest .exe installer from Logitech, run it as an Administrator, and let it detect your hardware natively.

FAQs

1. Why is Logitech G Hub stuck on "Connect your Logitech G Gear"? This happens when the background G Hub updater services crash or when Windows silently replaces Logitech's proprietary USB drivers with a generic Microsoft mouse driver during a system update.

2. How do I force G Hub to detect my G502 Hero? Open Task Manager and forcefully end the LGHUB, LGHUB Agent, and LGHUB Updater processes. Then, right-click the G Hub desktop icon and select "Run as Administrator" to force a fresh hardware scan.

3. What is the hard reset button combination for the G502 Hero? If your G502 is glitching, hold down the Left Mouse Button (LMB), Right Mouse Button (RMB), and the middle DPI button (the G9 button behind the scroll wheel) simultaneously for 5 to 10 seconds while G Hub is open to force a hardware reset.

4. Does using a USB hub stop G Hub from detecting my mouse? Yes. Unpowered USB hubs, keyboard passthroughs, or front-panel case headers often fail to deliver consistent voltage or data packets. Always plug your G502 directly into the rear I/O shield of your motherboard.

5. Why does Windows Device Manager show my G502 as a generic "HID-Compliant Mouse"? Windows sometimes overrides third-party drivers. You must right-click the "HID-Compliant Mouse" in Device Manager, click "Uninstall Device," unplug the G502, restart your PC, and plug it back in to force Windows to fetch the correct Logitech driver.

6. Will reinstalling Logitech G Hub delete my macros and DPI profiles? If you uninstall G Hub normally, it will delete your local profiles. To save them, ensure you are logged into a Logitech account within the app so your profiles are backed up to the cloud before you uninstall.

7. Why does my G502 Hero work, but it doesn't show up in the software? The mouse has built-in onboard memory, allowing it to function as a basic mouse with default DPI steps even without software. If it works but isn't showing up, the issue is strictly a software corruption within the G Hub agent.

8. Is Logitech Gaming Software (LGS) better than G Hub for the G502? While many users prefer the older LGS interface, Logitech no longer actively updates it. The newer G502 Hero models are specifically engineered to interface with G Hub, and using the outdated LGS can cause compatibility issues.

9. Can third-party RGB software interfere with G Hub? Yes. Software like Corsair iCUE, Razer Synapse, or Asus Armoury Crate can fight for control over USB headers. Try temporarily disabling other RGB software to see if G Hub recognizes your mouse.

10. How do I fix G Hub getting stuck on the loading animation? This is a common bug where the updater fails to unpack. You must navigate to C:\Program Files\LGHUB, delete the folder entirely, and run a fresh installer downloaded directly from the official Logitech website.
