Device descriptor request failure is an annoying issue that shows up when connecting your device to a laptop or computer. Thankfully, there exist multiple approaches that you can employ to swiftly and effortlessly resolve the issue. This article will walk you through the steps necessary to troubleshoot and solve this issue in Windows. 

What is Device Descriptor Request Failure? 

Device Descriptor Request Failure is a common issue experienced by Windows users when a connected hardware device, such as a USB or an external hard drive, is not recognized by the system. The problem lies within the device descriptor – a report that provides essential information about the device to the operating system. If this report fails to get the acknowledgment, then Windows cannot recognize the device, and thus, an error occurs. 

This might be attributed to various reasons, such as outdated system drivers, incorrect system settings, or hardware issues. It’s akin to a doorman not recognizing a guest because he doesn’t have the guest list. 

The good news is, despite sounding complex, the solutions to this problem are quite straightforward and can be performed even by non-tech-savvy users. Just as a doorman could call the host to confirm the guest’s identity, your computer has ways to re-establish connection with the unrecognized device. Let’s dive further and explore these solutions. 

Fix Device Descriptor Request Failure on Windows

To fix the device descriptor request failure in Windows, numerous steps are available for you to follow. These methods are quite simple and you don’t need to be an IT guru to apply them.

Method 1: Restart Your Computer 

You’d be surprised how many problems can be solved with a simple restart. It’s quick, easy, and often effective. By performing a system restart, you effectively reset the system and eliminate any temporary software glitches that may be responsible for the device descriptor request failure.

Method 2: Update Your Device Driver 

If the restart doesn’t work, there could be issues with your device drivers. These are software components that facilitate the communication between your computer and hardware devices. If they’re outdated or corrupted, they could cause problems. You can update your drivers manually by visiting the manufacturer’s website and downloading the latest version, or you can use a driver update tool to do it automatically.

Method 3: Use the Device Manager 

The Device Manager in Windows is a handy tool that allows you to view and control the hardware attached to your computer. If you’re experiencing the device descriptor request failure, you can use the Device Manager to check the status of your device and perform troubleshooting steps.

Method 4: Check Your USB Port and Cable

On occasion, the issue may not originate from your computer or device but rather from the connection between them. Check to make sure your USB port is functioning correctly by plugging the device into a different port. Similarly, check your USB cable for any signs of damage.

Remember, the key is to be patient. These problems can be frustrating, but with a bit of trial and error, you should be able to fix the device descriptor request failure. If all else fails, don’t hesitate to reach out to professional tech support. 


The device descriptor request failure can be frustrating, but there are a few steps you can take to try and fix it. Start by restarting your computer and updating your drivers.
