If you’re seeing this error, don’t worry! This step-by-step guide will walk you through the most effective ways to resolve the issue.
What is Windows System Error Code ERROR_331?
Before diving into solutions, it’s helpful to understand what ERROR_331 means.
- Error Code: 331
- Description: "Device is not connected."
- Common Cause: This error often appears when Windows attempts to communicate with a connected device but fails because the device is either disconnected, malfunctioning, or its driver is problematic.
Understanding this helps us target the problem areas logically — device connectivity and driver stability.
Step-by-Step Guide to Fix ERROR_331
Step 1: Restart Your Computer
Sometimes, the simplest fix is the best fix.
- Save your work.
- Restart your computer.
- Check if the error persists.
Why?
Temporary glitches or conflicts sometimes cause device communication errors. A restart refreshes system processes and can clear out such issues.
Step 2: Check Physical Connections
Confirm that the device causing the problem (external hard drives, USB devices, external peripherals) is properly connected.
- Unplug the device.
- Inspect the cable and ports for damage or dirt.
- Reconnect securely.
- If possible, try connecting to a different USB port or another computer.
Pro Tip:
Loose or dirty connectors are among the most overlooked causes. Cleaning the port gently with compressed air can also help.
Step 3: Run the Windows Troubleshooter
Windows offers built-in troubleshooters that automatically detect and fix common hardware and device issues.
- Press Windows key + I to open Settings.
- Go to Update & Security > Troubleshoot > Additional troubleshooters.
- Select Hardware and Devices > Run the troubleshooter.
- Follow the on-screen instructions and apply recommended fixes.
Step 4: Update or Reinstall Device Drivers

- Follow prompts and restart if instructed.
Reinstall Drivers:
If updating doesn’t help:
- In Device Manager, right-click the device and select Uninstall device.
- Confirm by checking Delete the driver software for this device.
- Restart your PC. Windows will attempt to reinstall the driver automatically.
Step 5: Check Device Status in Device Manager
In Device Manager:
- Right-click the device and select Properties.
- Under the General tab, check the Device status box.
- If it shows any error messages or codes, note them down for further research or support.
This status can provide clues if the device is disabled, needs firmware updates, or has conflicts.
Step 6: Disable Power Management for USB Devices (If Applicable)
Sometimes, Windows powers down USB devices to save energy, causing communication issues.
- Open Device Manager.
- Expand Universal Serial Bus controllers.
- For each USB Root Hub or Generic USB Hub:
- Right-click > Properties.
- Go to the Power Management tab.
- Uncheck Allow the computer to turn off this device to save power.
- Restart your PC.
Step 7: Scan for Malware
Malicious software can interfere with hardware communication.
- Run a full system scan using Windows Defender or your preferred antivirus.
- Remove any threats detected.
- Restart your machine and test again.
Step 8: Perform System File Check (SFC)
Corrupted system files can cause unexpected errors.
- Open Command Prompt as Administrator (Right-click Start > Command Prompt (Admin) or Windows Terminal (Admin)).
-
Type the following and press Enter:
sfc /scannow
- Wait for the process to complete.
- If issues are detected and fixed, restart your PC.
Step 9: System Restore (Last Resort)
If ERROR_331 started appearing recently, rolling back your system to a previous state might help.
- Press Windows key + R, type
rstrui.exe, and press Enter. - Follow the prompts to choose a restore point before the error began.
- Complete the process and restart.
