USB devices make it easy to connect flash drives, external hard drives, keyboards, mice, printers, smartphones, webcams, and many other peripherals to your computer. However, sometimes Windows 11 or Windows 10 displays an error such as “USB Device Not Recognized”, “The last USB device you connected to this computer malfunctioned”, or simply fails to detect the connected device. As a result, the USB device may not appear in File Explorer, Device Manager, or the connected application.
This problem can occur due to faulty USB ports, damaged cables, outdated USB drivers, power management settings, corrupted system files, or problems with the USB device itself. Fortunately, most USB recognition issues can be resolved by checking the hardware connection, reinstalling USB drivers, updating Windows, or adjusting power settings.
This guide explains the best methods to fix the “Windows Doesn’t Recognize USB Device” error in Windows 11 and Windows 10.
What Causes Windows Not to Recognize a USB Device?
When you connect a USB device, Windows installs the required drivers and assigns system resources so the hardware can function correctly. If this process fails, the operating system cannot identify or communicate with the device.
Common causes include:
- Faulty USB port
- Damaged USB cable
- Corrupted USB drivers
- Outdated chipset drivers
- USB power management issues
- Corrupted Windows system files
- Incompatible USB device
- Insufficient power for the USB device
- Outdated BIOS or firmware
- Hardware failure of the USB device
Method 1: Reconnect the USB Device
A temporary connection issue can prevent Windows from detecting the device. Disconnecting and reconnecting the USB device often forces Windows to detect it again.
If possible, test the device on another USB port to determine whether the problem is related to the port or the device itself.
Follow these steps:
- Disconnect the USB device.
- Wait about 10 seconds.
- Reconnect it securely.
- Try another USB port.
- If available, test both USB 2.0 and USB 3.0 ports.
- Avoid using a USB hub during testing.
- Check whether Windows detects the device.
If the device is recognized, the issue was likely a temporary connection problem.
Method 2: Restart Your Computer
Windows may temporarily fail to initialize USB controllers after an update or system error. Restarting the computer reloads USB services and drivers.
This simple step often resolves temporary USB detection problems.
Follow these steps:
- Save your work.
- Click Start.
- Select Power.
- Choose Restart.
- After Windows starts, reconnect the USB device.
- Check whether it is recognized.
If the issue remains, continue to the next method.
Method 3: Run the Hardware and Devices Troubleshooter
Windows includes troubleshooting tools that can detect and repair common hardware problems automatically.
Although the Hardware and Devices troubleshooter is hidden in newer Windows versions, it can still be launched using a command.
Follow these steps:
- Press Windows + R.
- Type the following command:
msdt.exe -id DeviceDiagnostic- Press Enter.
- Click Next.
- Allow Windows to detect hardware problems.
- Apply any recommended fixes.
- Restart your computer.
Reconnect the USB device and check whether it is detected.
Method 4: Reinstall the USB Drivers
Corrupted USB drivers are one of the most common reasons Windows fails to recognize connected devices.
Reinstalling the drivers allows Windows to automatically install fresh copies during the next startup.
Follow these steps:
- Right-click the Start button.
- Select Device Manager.
- Expand Universal Serial Bus controllers.
- Right-click each USB Root Hub.
- Select Uninstall device.
- Repeat for any devices showing a warning icon.
- Restart the computer.
- Allow Windows to reinstall the drivers automatically.
Reconnect your USB device after Windows finishes loading.
Method 5: Disable USB Selective Suspend
USB Selective Suspend allows Windows to save power by temporarily disabling inactive USB ports. Occasionally, this feature may prevent certain USB devices from reconnecting properly.
Disabling the feature can improve USB detection, especially for external drives and older peripherals.
Follow these steps:
- Open Control Panel.
- Click Power Options.
- Select Change plan settings.
- Click Change advanced power settings.
- Expand USB settings.
- Expand USB selective suspend setting.
- Set it to Disabled.
- Click Apply.
- Click OK.
- Restart the computer.
Reconnect the USB device and test it again.
Method 6: Update USB and Chipset Drivers
Outdated chipset and USB controller drivers can cause compatibility issues with newer hardware.
Installing the latest drivers from your computer or motherboard manufacturer improves hardware compatibility and stability.
Follow these steps:
- Visit your computer or motherboard manufacturer’s support website.
- Search for your exact model.
- Download the latest chipset drivers.
- Download the latest USB controller drivers if available.
- Run the installer.
- Restart the computer.
- Reconnect the USB device.
Check whether Windows now recognizes the device.
Method 7: Check the USB Device on Another Computer
Testing the USB device on another computer helps determine whether the problem lies with Windows or the hardware itself.
If the device is not detected on multiple computers, the device or its cable may be faulty.
Follow these steps:
- Disconnect the USB device.
- Connect it to another Windows computer.
- Wait for Windows to detect it.
- Test whether the device functions normally.
- If available, try a different USB cable.
- Return to the original computer if the device works elsewhere.
This helps isolate whether the issue is hardware- or software-related.
Method 8: Repair Windows System Files
Corrupted system files can interfere with USB driver installation and hardware detection.
Running the System File Checker and DISM tools repairs damaged Windows components.
Follow these steps:
- Open Command Prompt as Administrator.
- Run:
sfc /scannow- Wait for the scan to complete.
- Then run:
DISM /Online /Cleanup-Image /RestoreHealth- Restart the computer.
- Connect the USB device again.
If damaged system files were responsible, Windows should now recognize the device.
Method 9: Install the Latest Windows Updates
Microsoft regularly releases updates that improve USB compatibility, hardware drivers, and system stability.
Installing the latest updates may resolve known USB recognition issues.
Follow these steps:
- Open Settings.
- Click Windows Update.
- Select Check for updates.
- Install all available updates.
- Restart the computer.
- Reconnect the USB device.
Verify whether the device is now detected.
Conclusion
If Windows 11 or Windows 10 doesn’t recognize a USB device, the problem is often caused by a faulty connection, corrupted USB drivers, outdated chipset software, or power management settings. Start by reconnecting the device, trying another USB port, and restarting your computer. If the issue continues, reinstall the USB drivers, disable USB Selective Suspend, update chipset drivers, and repair Windows system files using SFC and DISM. Testing the USB device on another computer is also an excellent way to determine whether the issue is with the device or the PC. By following these methods, you can restore USB functionality and reconnect your flash drives, external hard drives, printers, keyboards, and other USB peripherals.
Frequently Asked Questions
1. Why does Windows say “USB Device Not Recognized”?
This usually happens because of corrupted USB drivers, faulty USB ports, damaged cables, power management issues, or a malfunctioning USB device.
2. Can a damaged USB cable prevent Windows from recognizing a device?
Yes. A damaged or low-quality USB cable can interrupt data communication even if the device still receives power.
3. Will reinstalling USB drivers delete my files?
No. Reinstalling USB controller drivers only refreshes the driver software and does not affect files stored on USB drives.
4. How can I tell if the USB device is faulty?
Connect it to another computer. If it isn’t recognized there either, the USB device or its cable is likely defective.
