1. Check Physical Connections and USB Hardware

Ensure the issue isn't caused by faulty cables, damaged ports, or drive malfunctions. A secure physical connection is essential for device recognition.

• Try connecting the USB drive to another computer to verify if it's detected.
• Use a different USB cable if the drive uses one, especially for external hard drives.
• Test multiple USB ports on your Windows 11 device to rule out port-specific failures.
• Ensure the USB drive's LED light (if available) turns on when plugged in.

2. Restart Windows Explorer via Task Manager

Windows Explorer manages file system interactions and may fail to refresh connected devices. Restarting it can reinitialize USB detection without rebooting the system.

• Press Ctrl Shift Esc to open Task Manager.
• Locate "Windows Explorer" under the Processes tab.
• Right-click it and select "Restart".
• Wait a few seconds and reconnect the USB drive to see if it appears.

3. Update or Reinstall USB Drivers

Outdated or corrupted USB drivers can prevent proper device detection. Updating or reinstalling them restores communication between the OS and hardware.

• Press Windows X and select "Device Manager".
• Expand the "Universal Serial Bus controllers" section.
• Right-click each USB Root Hub and select "Update driver".
• If updating doesn't work, right-click and choose "Uninstall device", then restart the PC to reinstall drivers automatically.

4. Run the Hardware and Devices Troubleshooter

This built-in diagnostic tool identifies and resolves common hardware issues, including USB detection problems.

• Go to Settings > System > Troubleshoot > Other troubleshooters.
• Find "Hardware and Devices" and click "Run".
• Follow the on-screen instructions and apply recommended fixes.
• Allow the troubleshooter to restart services or adjust settings automatically.

5. Assign or Change Drive Letter via Disk Management

Conflicting or missing drive letters can make a USB invisible in File Explorer, even if the system detects it internally.

• Press Windows X and select "Disk Management".
• Locate your USB drive in the list (usually labeled as "Removable").
• If it has no drive letter, right-click the partition and choose "Change Drive Letter and Paths".
• Click "Add" and assign an available letter (e.g., E:, F:).
• Check File Explorer to see if the drive now appears.

6. Disable USB Selective Suspend Setting

This power-saving feature may disable USB ports to conserve energy, causing intermittent or failed device detection.

• Open Settings > System > Power & sleep > Additional power settings.
• Select your current power plan and click "Change plan settings" > "Change advanced power settings".
• Expand "USB settings" > "USB selective suspend setting".
• Set both "On battery" and "Plugged in" to "Disabled".
• Click Apply, then reconnect the USB drive.
