Device Descriptor Request Failed | Windows 7/8/10 | Code 43

Hello Friends! Welcome to another blog of Gossipfunda. Through our blogs, we try to make you clear and confident with the technical terms you face usually in your day-to-day lives. One of my friends asked me to solve an error which she was facing for a long time. She informed me that whenever she tried to plug in any USB-drive or USB- cable on her Windows laptop, a dialog box popped up on the laptop’s screen with the error as ‘USB Device Descriptor Request Failed.’ She has a Windows 10 operating system. Then I did thorough research on this issue and came with some useful solutions along with some terms which should be known. I resolved my friend’s problem and explained to her some of the technicalities. Also, I thought to share my knowledge with the Gossipfunda family because you people sound technical indeed.

This blog is dedicated to another error that people face generally which is ‘USB device descriptor failed’ or ‘Device Descriptor Request Failed’ or ‘Code 43’. We will try to explore as many new terms as we can. We will definitely go through the solutions to fix this issue. Along with this, we will also try to understand the root cause of this issue. If we get some other terminology related to this topic, then we will try to dive into them too. So, this is going to be a very descriptive blog with a wide range of content.

Do you know what the Device Descriptor is?

The device descriptor also known as USB_DEVICE_DESCRIPTOR is the base of the descriptor tree and contains overall details of a USB artifice.

A USB (Universal Serial Bus) device should avail a sole descriptor. This device descriptor conveys pertinent details of the device like vendor identifier (idVendor), product identifier (idProduct). Such information is used by Windows to build a hardware Id of that particular device. The device descriptor also displays the sum total of configurations supported by the device. To see hardware id:

  • Open ‘Device Manager‘ to check device properties.
  • Next, click on the ‘Details’ tab. Here you will see the ‘Hardware Ids’ attribute that is indicated as “USB\XXX”. This is the Id generated by the operating system that is Windows. Here you will find some other details as well. Let us try to understand them too in brief.

Here one property is bcdUSB. It shows the USB version specification that the device obeys. For example, 0x0200 implies that the device is manufactured according to USB 2.0 specs. The bcdDevice attribute specifies the device- defined revision number. The USB driver utilizes idVendor, idProduct and bcdDevice to produce compatible and hardware Ids for the device.

What does ‘Device Descriptor Request Failed’ error mean?

It really gets frustrating when we face some unwanted errors while we are in a serious mood to do work efficiently. But don’t worry. Let us make few attempts to settle down your problem. First let us understand what this issue is and why this occurs.

The ‘Device Descriptor Request Failed’ or ‘Unknown USB Device’ is an issue of Device Manager of Windows operating system. Currently, the device state is displayed as “Windows has stopped this device because it has reported problems (Code 43). A request for the USB device descriptor failed.” ‘Code 43’ is the error generally displayed whenever the operating system senses any problem with the software or hardware of the system. This issue comes under the ‘Universal Serial Bus controllers’ segment. This error credibly conveys that the device driver has informed the Windows OS that the device failed. This error can also pop up when the device driver fails or the device hardware fails.

In simple words, if the USB device is not detected by the USB port properly, then we can face such types of errors. This means we have to coordinate between the device and the port. And if there exists any problem in the hardware or the system settings, we need to fix them by finding out the loophole. A device may also convey different details if it is plugged in a port of high-speed capacity than the information it conveys when it is inserted in the port compatible with its full speed capacity. For example, USB 3.0 port supports USB 2.0 specified USB devices, but there can be the possibility of conveying wrong information.

How to fix ‘Device Descriptor Request Failed’?

As I went through various sites, videos and content, I came to know that this issue is common in Windows 7, Windows XP, Windows 8, and Windows 10. This implies that all of the Windows’ versions have this error in common. Hence the fixes are version-free. By this I mean to say that solutions listed below are valid for all the versions of Windows operating system. We shall start with some easy and quick methods because many times easy steps can be the solution and by escaping them, we put our head in the extremities. Then we shall also go through some advanced methods. Let us now discuss the fixes without any further delay.

Quick Fixes

Firstly, we will try our traditional trial and error method. The reason for the error might be a damaged USB device or it may also be possible that the USB port has some fault. Is it broken or there is some internal matter that is causing the problem? We have the option of troubleshooting. But before that you can try the following ways:

  1. If you are sure that the ports of your system are absolutely fine as other USB drives were working flawlessly, then test the particular drive on other systems as well to confirm its malfunctioning.
  2. Take a tested working USB device, try to attach it to the USB port, and check whether it is working or not functioning at all.

In the overhead content we tried to plunge into the system and settings of any laptop or desktop that has Windows operating system. It can be any one among the Windows 7, Windows 8 and Windows 10. Then we understood one of the errors which are either due to malfunctioning of hardware or any error in the software. In the further sections we went through some of the methods to fix such types of errors.

Meanwhile, I also tried to boost your awareness about the typical terminology of interior and exterior of one of the most useful inventions in electronic gadgets that are laptops/desktops. So, this is my firm belief that we should try to explore each and every loophole and each and every aspect of anything we face in our lives. This makes us confident and groomed up as an individual as well as we become capable of solving issues faced by others. As being a social animals, our top priority must be to contribute to society in all possible ways we can. So, this was a social lesson from my side at the end of the blog.
