Table of Contents :

The "Device Descriptor Request Failed" error is a common issue that Windows users may encounter when connecting USB devices. This error can be frustrating, particularly if you're trying to transfer files or use a peripheral like a printer, scanner, or external hard drive. In this guide, we'll explore what this error means, its potential causes, and detailed troubleshooting steps to help you resolve the issue.

Understanding the Device Descriptor Request Failed Error

When you plug a USB device into your computer, the operating system tries to read the device's descriptor, which contains vital information about the device, such as its type, manufacturer, and capabilities. If the computer cannot read this descriptor correctly, you receive the "Device Descriptor Request Failed" error.

Common Symptoms

  • Error message: You will often see the message "Device Descriptor Request Failed" in the Device Manager.
  • Unrecognized device: The device may not be recognized at all, or it might show up with a yellow exclamation mark.
  • Device malfunction: The device might work intermittently or not at all.

Causes of Device Descriptor Request Failed

Understanding the potential causes can help in troubleshooting effectively. Here are some common reasons why this error may occur:

  • Faulty USB cable: Sometimes, the cable connecting your device to the computer may be damaged.
  • Defective USB port: A malfunctioning USB port can hinder communication between the device and the computer.
  • Driver issues: Outdated or corrupted drivers can lead to communication problems.
  • Power supply problems: Insufficient power supply to the USB device can cause descriptor requests to fail.
  • Conflicts with other devices: Conflicting USB devices may interfere with the recognition of your device.

Troubleshooting Steps

Here’s a step-by-step troubleshooting guide to help resolve the "Device Descriptor Request Failed" error:

Step 1: Check the USB Device and Connections

  1. Inspect the USB cable: Look for any signs of wear or damage. If possible, try using a different USB cable to see if that resolves the issue.
  2. Test a different USB port: Plug the device into a different USB port on your computer. If it works in a different port, the original port may be defective.
  3. Try the device on another computer: This can help you determine if the issue is with the device itself or your computer.

Step 2: Power Cycle the Device

Sometimes, simply power cycling the device can help. Follow these steps:

  1. Disconnect the USB device from the computer.
  2. Turn off the device (if it has a power switch).
  3. Wait for at least 30 seconds.
  4. Reconnect the device and turn it back on.

Step 3: Update USB Drivers

Outdated or corrupted drivers can cause this error. To update your USB drivers, follow these steps:

  1. Right-click on the Start button and select Device Manager.

  4. Disconnect the USB device.
  5. Restart your computer, and then reconnect the USB device. Windows should automatically detect and reinstall the necessary drivers.

Step 5: Disable USB Selective Suspend Setting

The USB selective suspend feature can sometimes interfere with device recognition. Here’s how to disable it:

  1. Press Windows + R to open the Run dialog box, type control, and press Enter to open Control Panel.

Keeping your operating system up-to-date can resolve many issues, including driver-related problems:

  1. Go to Settings > Update & Security > Windows Update.
  2. Click on Check for updates. Install any available updates and restart your computer.

Step 7: Run Hardware Troubleshooter

Windows includes a built-in troubleshooter that can automatically detect and fix common hardware issues:

  1. Open Settings.
  2. Click on Update & Security.
  3. Select Troubleshoot from the left menu.
  4. Click on Additional troubleshooters.
  5. Locate and run the Hardware and Devices troubleshooter.

Step 8: Check for Power Management Settings

Sometimes, power management settings can cause USB devices to fail. To check:

  1. Go back to Device Manager.
  2. Right-click on each USB Root Hub listed under Universal Serial Bus controllers.
  3. Select Properties.
  4. Go to the Power Management tab and uncheck the box that says Allow the computer to turn off this device to save power.

  • Test with different devices: If possible, test the USB port with other devices to confirm the port's functionality.
  • Check for conflicts: Make sure no other devices connected to the USB ports are causing a conflict.

When to Seek Professional Help

If you have tried all the troubleshooting steps above and are still encountering the "Device Descriptor Request Failed" error, it may be time to seek professional help. The issue could be a sign of hardware failure in either the USB device or the computer's motherboard.
