{Solved} 5 Ways to Fix USB Device Descriptor Failed Error

USB Device Descriptor Failed Error is a widespread issue. But don’t worry, as we have 5 Ways to Fix USB Device Descriptor Failed Error. After following one of these ways, you can overcome this problem. One of the many benefits of possessing a traditional laptop is that they did not use to skimp on the ports back then.

The Device Descriptor, also referred to as USB_DEVICE_DESCRIPTOR, is a fundamental aspect of the descriptor tree. It offers crucial details about the device, like its distinct idVendor and idProduct numbers. These details help the Windows operating system recognize and install the correct device driver.

However, there is one issue with ageing laptops, which now seems to be the case with newer models. It’s the Request for the USB Device Descriptor Failed. Sometimes, when you connect your favourite USB peripherals, such as a web camera or even a standard mouse, you might see a message pop up in the system tray as a dialogue, which says something like unknown USB device (device descriptor request failed), even though it undoubtedly should not be an unknown device.

How to Fix USB Device Descriptor Failed Issue

If you have an older laptop as your primary computer, you will know the luxury of still having a VGA port for connecting old-school monitors. At the same time, these newbies, with their slim notebooks, fiddle with dongles and adapters.

This error might have been raised because of some hardware issue with your PC or Laptop. New or old, no system is safe! From problems, I mean (I have been watching those Russian blackhat hacker movies again, sorry!). See Also: Is Softonic Safe to Download? Pros and Cons

Anyway, CIA dialogues aside, how about we try to do something about this USB Device Descriptor Failed problem, eh? Here are five methods you can follow to restore your system IO to its former glory, hopefully. Let’s get on with it, then.

Method 1: Remove your Power Supply

Weirdly enough, your innocent-looking laptop power brick or the main supply itself can sometimes cause IO ports and their BUS lines to start tripping out. So, this method will automatically fix the problem if the Power Supply causes the problem in the first place.

1. Pull out the Power Supply plug from the Laptop. 2. Restart the computer and connect the USB device to any USB port. I suggest linking it to the one you did earlier and getting the USB Device Descriptor Failed message.

3. After that, plug in the Power Supply and see if the device works.

If not, restart your system again by unplugging everything, and then connect only the USB peripheral without the power supply cord, and see if you still see that USB Device Descriptor Failed with that yellow triangular warning sign. If both these methods do not work, head on to the next one.

Method 2: Uninstall the respective USB Driver in the Device Manager

Sometimes, your USB driver can get nasty and stop working usually. In those cases, instead of trying to repair the things, it’s faster and easier to uninstall them. Windows has this functional ability, automatically installing the necessary drivers for simple, recognizable devices without you having to do anything. So, let’s see if uninstalling the USB driver from your system works. To do that, follow these steps:

1. First, open the Device Manager by typing devmgmt.msc in the Run window (Win+R). Once the device management window opens up, you need to expand the category Universal Serial Bus Controllers and locate the wrong USB device, which was showing the USB Device Descriptor Failed error sign and was not appropriately recognized by the Windows operating system.

2. Once you find it, just right-click on the device and then select the Uninstall option from the right-click context menu.

3. After it is done being uninstalled, go ahead and restart your PC. As mentioned, the Windows operating system will automatically reinstall those device drivers.

Method 3: Update the USB Driver

The USB Device Descriptor Failed issue can also arise when the driver misbehaves occasionally and works OK other times. This is more annoying than the thing not working at all because you never know if your USB device will get recognized or not, each time you find the need to plug it in.

In this case, updating the driver would fix the problem. So, if uninstalling and reinstalling the same version did not help much with that USB device, maybe you need to update the driver.

Updating a driver is just as simple as uninstalling it from the earlier method. To do that, follow these steps.

Run the tool and click the Scan Now button. Driver Easy software will now scan your PC and detect any problem drivers.3. Click on the Update button near a USB driver which is flagged as outdated.

1. Press the Win+R keys at the same time. The Run box will pop up.

2. Type in control in the text box of the run window and click the OK button or hit the Enter key. It will open the Control Panel.

5. Now, click on Change settings that are currently unavailable.

6. Under the Shutdown settings, you will find a box next to the Turn on fast startup (recommended). Uncheck it and then, click on the Save changes button on the bottom right end.

7. Once that’s done, restart your computer and see if the problem resolves. Note your PC will usually reboot a little slower than usual, so be patient.

Method 5: Change the USB Selective Suspend Settings

Your computer (and all other computer systems) selectively suspends the bus lines that are not in use to save power and reserve CPU clock cycles. It is possible that the system suspended that USB device once in a session and did not refresh after that for some reason, leading us to have the USB Device Descriptor Failed error. To change the USB selective suspend settings, follow these simple steps:

1. Go to Power Options again and click on Show additional plans.

2. Click on the Change settings that are currently unavailable link to be able to change the setting which is presently not clickable.

3. Select High Performance and click on Change Plan Settings.

4. Click on Change advanced power settings.

5. Locate the USB settings option and then click to expand it.

6. Next, expand the USB selective suspend setting. There, disable both the On battery and the Plugged-in settings.

7. Finally, click Apply and restart your PC.
