How to Fix Mouse Not Detected by Windows or Software

1. Why Is Your Mouse or Software Not Detecting It?

Detection failures usually fall into two categories:

2. Fix 1: Disable Windows USB Selective Suspend

Windows aggressive power management can put USB root hubs into low-power sleep states, disconnecting your mouse:

1. Press Win + X and select Device Manager.
2. Expand Universal Serial Bus controllers.
3. Right-click each USB Root Hub → Properties → Power Management tab.
4. Uncheck "Allow the computer to turn off this device to save power" and click OK.

3. Fix 2: Reinstall HID-Compliant Mouse Driver

Corrupted driver entries prevent Windows from establishing the input pipe:

1. In Device Manager, expand Mice and other pointing devices.
2. Right-click HID-compliant mouse and select Uninstall device.
3. Unplug the mouse USB cable or wireless dongle, wait 5 seconds, and plug it back in. Windows will cleanly reinstall the generic driver.

4. Fix 3: Fix Companion App Detection (G HUB / Synapse)

If companion software hangs on "Connecting" or fails to detect your mouse model:

• Press Ctrl + Shift + Esc to open Task Manager. End all related processes (e.g. LGHUB.exe, LGHUB Agent, Razer Synapse Service).
• Relaunch the application by right-clicking its desktop shortcut and choosing Run as Administrator.

5. Fix 4: Re-Pair 2.4 GHz Wireless Dongle

If a wireless mouse loses sync with its dedicated USB receiver, use the manufacturer's official pairing utility (e.g. Logitech Onboard Memory Manager / Razer Pairing Utility) to re-bind the mouse hardware ID to the USB dongle.

6. Fix 5: Use Onboard Memory Mode as Permanent Fallback

To prevent ongoing detection headaches, configure your preferred DPI (e.g. 800 DPI) and 1000 Hz polling rate once inside Onboard Memory Mode, then uninstall or close the heavy background companion software completely.
