How To Fix USB Device Descriptor Request Failed Error
Your computer may suffer from this error because of various reasons. As a result, some users may need to try different methods until they find the cause for their computers’ error.
Your mission now is to follow our instructions carefully and try one method at a time until you completely fix the problem.
Before starting trying these methods below, please remember that with a USB hub or mixed 2.0 vs. 3.0 USB ports, you should plug these USB devices directly into the 3.0 port for the first try.
Now, let’s get started with our methods.
Checking The Power Supply
The crucial thing to remember about this method is that you can only try it if your device is portable, like a laptop. In some cases, following these simple steps below will help you quickly fix this Unknown USB device failure on Windows 10.
First, you need to unplug the power supply of the device temporarily. Then, connect your computer with the problematic equipment.
After that, make your computer run on the integral battery by disconnecting all the charging cables from it. Finally, plug your USB device and wait for the system to check and recognize it.
When you see that your USB is ready to work again, it would be appropriate to replace the charger set. However, if you still see the problem after all those steps, this method is not the right one for your USB device. At this point, you know for sure that the power supply is not the cause.
Here are detailed steps for fixing the problem instantly:
- Disconnecting the laptop’s power plug.
- Insert the supply once again.
- Reboot the computer.
- Connect the USB to the port.
Examine Issues From The Hardware
It is likely that due to a hardware problem, you are unable to use your USB device. This problem means that the failure doesn’t come from the operating system but inside your computer.
To check if this is the reason or not, here are the two basic ways. Through them, you will know whether it is necessary to consider restoring your computer or you need to try other methods in our post.
Try plugging into another USB port. If the device starts to work normally again, the original port is most likely the cause. Our advice is to mark that not-functioning port or replace it immediately.
Try plugging into another computer. Use the same hardware on this computer and check if the device can work properly. If not, the device can not operate effectively anymore, and you need to replace or repair it. Otherwise, the system issue is the reason for the error.
After checking with these two steps, you can decide whether or not to follow other methods. The next methods are for issues from the software, so it means that the error will come from your computer’s operating system.
