Windows 8.1 handle request failed. Resolving the error “USB device descriptor request failed. Checking power consumption and relieving static electricity

When using various USB devices, a device descriptor request failure error may occur. In Device Manager, this component will appear with a warning symbol and error code 43 in the description. This may be accompanied by incorrect operation of the USB port of your computer - the flash drive is not detected, the gamepad does not connect, the Web camera does not work, and everything is accompanied by a failure of the descriptor request and error 43.

There are several reasons in this case:

Hub failure
Crash USB drivers port (most often version 3.0) or chipset driver
Low power or power settings error
Physical damage to the port

Some of the reasons listed may be software error, but there are also cases when you have to clean the ports or carry the device to service center for repair.

Hub failure

A hub (Generic USB Hub) is a device for connecting several USB connectors through one port, or, more simply, a splitter. This name also refers to the connector on motherboard for connecting “external” USB ports.
The failure may occur as a result of incorrect updating of chipset or hub drivers. Most often, this kind of error occurs when using software for automatic installation and driver updates such as Driver Solution Pack and others, so you need to be extremely careful when using such applications.
To solve this problem you need to install previous version drivers. Go to Device Manager, select Generic USB Hub and click Update Driver.

Then search for drivers on this PC.

Then when selecting from the list compatible devices install the one suggested by the system.
This video may help you to complete the steps.

It is worth noting that there may be several hubs in the system and these manipulations must be carried out with each one.

Chipset USB port driver failure

In Device Manager, select the failed controllers and remove them; after reboot, the system can automatically configure this equipment correctly and download the appropriate drivers through the Update Center.
You can try running the Hardware or Device troubleshooter. Go to Control Panel and open Troubleshoot, display all categories and run the necessary utility.

If the error troubleshooter did not help, then proceed to updating the drivers, you need to go to the website of the manufacturer of your computer (laptop, all-in-one or motherboard) and select the ones required for your PC. USB 3.0, Intel\AMD chipset driver and other drivers from the Chipset or USB tab should be suitable. The ACPI driver may also be suitable, since it is responsible for the power configuration.
Programs from the previous error description can also help us - Driver Solution Pack, Driver Booster and others. These applications can either cause an error or solve it, so their use should be extremely careful.

Setting up the power supply

There are cases when the connector does not have enough power and for this reason it does not work correctly, to fix this problem in the Power Options you need to set the High Performance mode or the performance mode provided by the motherboard or computer manufacturer (ACPI). For large quantities USB connectors There may simply not be enough power for one hub or the distribution will be incorrect.

Some sites advise turning on the option “Allow the computer to turn off this device to save energy” in the controller’s power settings.

and also prohibit temporary disabling of the port in the electrical circuit parameters.

Solving the descriptor error problem in this way is doubtful, but it’s worth a try.
You can also try completely de-energizing the device:

In the case of a laptop, this means turning off the device and disconnecting the battery for 10-15 minutes.
If the motherboard, then turn off the PC and reset CMOS batteries, remove for 10-15 minutes and reconnect.

Physical damage

A last resort if the above methods did not help. The most “inconvenient” option, because on the motherboard you can change the hub connector, but on the laptop - only repair.
You can also diagnose the operation of a particular port by connecting boot drive and trying to boot from it without logging in. If the download occurs, then the problem is still not hardware in nature and you can try to reinstall the system and check the operation on clean Windows.

Have a great day!

After connecting a USB device, users encounter a problem when it simply does not work. Device Manager shows it as an unknown USB device (device descriptor request failed) in Windows 10. The properties show the following device status: Windows system stopped this device because it reported a problem (Code 43).

This article will tell you how to solve the problem of a USB device descriptor request failure in the Windows 10 operating system. In essence, the problem for the user is very similar to the situation when. Often the problem lies precisely in non-working drivers. Additionally, you can configure energy saving for devices or turn off power to the computer.

Actually, a failure to request a USB device descriptor tells the user about a problem with connecting to the device itself. However, you should not worry right away, since most often in practice the reason was hidden in the incorrect operation of the drivers.

Updating USB Device Drivers

The first thing the user needs to do is update the drivers of all root USB hubs and composite USB devices. You can also use the methods in the instructions: . It was there that we searched for drivers using the ID of unidentified hardware.

As a result, the system should successfully update drivers for the selected device. Occasionally helps users automatic search updated drivers For desired device. The system will search latest versions drivers for the device on the user's computer and on the Internet.

Disable Power Saving for USB Devices

By default, the operating system is able to temporarily turn off power to USB ports to save energy. Previously, we already had to remove the permission to temporarily turn off the device to save energy in the event.

Using the task manager method of disabling USB power saving, the user will have to remove permissions on all USB root hubs. To automatically remove permission on all devices at once, you can use the method using Windows 10 power plans.

Performing a computer shutdown

Very often, the problem of a USB device descriptor request failure can be solved by simply turning off the power to the computer. The simplest and most reliable way to de-energize a computer is to completely disconnect the computer from the network with some features:

Disconnect all problematic USB devices from the computer and press the Shift execute Shutdown operating system.
Next, completely turn off the power to the computer and press the power button while holding it down for about 10 seconds.

After which you can safely turn on the computer and check the functionality of USB devices. Additionally, users can reset BIOS settings motherboard by first removing the battery or selecting the desired item in the BIOS interface. Resetting settings occasionally also helps solve various kinds of connection problems external USB-devices.

conclusions

Quite often, users encounter unknown USB devices in the device manager. Windows devices 10. At the same time, some USB devices give an unpleasant failure when requesting a device descriptor. If it also says in your properties that the system stopped this device because it reported problems with code 43, then we recommend that you use the solutions to the problem presented above.

If, when connecting something via USB in Windows 10 or Windows 8 (8.1) - a flash drive, phone, tablet, player or anything else (and sometimes just USB cable) you see in the device manager an Unknown USB device and a message about “Device descriptor request failed” indicating error Code 43 (in properties), in this instruction I will try to give working ways to fix this error. Another variant of the same error is a port reset failure.

If previous method worked, and after a while your Windows 10 or 8 again started writing about a device descriptor failure and code 43, an additional action can help here - disabling power-saving functions for USB ports.

To do this, just like in the previous method, go to the device manager and for all devices Generic USB Hub, USB Root Hub and Composite USB device Open "Properties" by right-clicking, and then on the "Power Management" tab, disable the "Allow the computer to turn off this device to save power" option. Apply the settings you have made.

USB devices malfunction due to power problems or static electricity

Quite often, problems with the operation of connected USB devices and failure of the device descriptor can be solved by simply turning off the power to the computer or laptop. How to do it for PC:

Remove the problematic USB devices, turn off the computer (by shutting down, it’s better to hold Shift while clicking “Shutdown” to turn it off completely).
Unplug it from the outlet.
Press and hold the power button for 5-10 seconds (yes, with the computer unplugged), release.
Plug your computer into the network and simply turn it on as usual.
Connect the USB device again.

For laptops in which the battery is removed, all steps will be the same, except that in point 2 “remove the battery from the laptop” will be added. The same method can help when (in the indicated instructions there are additional methods to fix this).

Chipset drivers

And one more thing that can cause a USB device descriptor request to fail or a port to reset fails is uninstalled official drivers for the chipset (which should be taken from the official website of the laptop manufacturer for your model or from the website of the computer motherboard manufacturer). Those that Windows 10 or 8 installs itself, as well as drivers from the driver pack, do not always turn out to be fully working (although in the device manager you will most likely see that all devices are working normally, with the exception of an unidentified USB).

Such drivers may include

Intel Chipset Driver
Intel Management Engine Interface
Various Firmware utilities specific for laptops
ACPI Driver
Sometimes, separate USB drivers for third-party controllers on the motherboard.

Don’t be lazy, go to the manufacturer’s website in the support section and check the availability of such drivers. If they are not available for your Windows versions, you can try the installation previous versions in compatibility mode (the main thing is that the bit depth matches).

On this moment this is all what I can offer. Did you find your own solutions or did something described work? - I will be glad if you share it in the comments.

Owners of PCs and laptops connect to ports every day USB various gadgets and devices from flash drives to TVs. The USB interface is one of the most common methods of communication between electronic devices. When you connect new hardware for the first time, Windows automatically detects it and finds the necessary drivers in its database, ensuring a correct connection. As usual, each device comes with a disk containing drivers suitable for a specific device. Often, the user does not have to bother with self-installation, since Windows itself identifies the equipment, after which it can begin working with it. Moreover, the newer the version of the operating system, the wider the range of its software. Learn how to fix the USB Device Descriptor Request Failed error.

Windows 10 contains basic drivers for large quantity devices that can be connected to a computer. Although the 10th version of Windows regularly automatically updates drivers, the interaction of the computer with a new (and sometimes with a previously connected) device is not always successful.

Users , 8, 10 often encounter the problem of the error “Device descriptor request failed” (code 43). When you try to connect USB equipment to your computer, the system simply does not see it. Then in the device manager, at the place of the name of the connected equipment, it is defined as unknown, and next to it the message “Device descriptor request failed, code 43” is displayed. This means that for some reason the system is unable to recognize device data necessary for the computer to work with external equipment.

Very often, error “code 43” appears after installation or Windows updates 10. It is possible that the whole issue is in the software. But the opportunity physical damage USB devices or computer connectors should not be discarded either.

This is what error code 43 looks like:

Reasons for error code 43:

malfunction of the USB device or connector;
drivers are outdated, damaged, or there is a conflict between them;
failure system files due to a virus or malware;
damage Windows registry 10 when installing or updating software.

A hardware descriptor request error (code 43) can appear for various reasons. To fix it, it is necessary to identify and eliminate the source of its occurrence, physically or programmatically.

The cause may be physical defects in the cable itself, its cable or contacts. The plug or connector may have become dirty or oxidized, which is why there is not sufficiently tight contact between them. In any case where the system does not identify the equipment, before correcting the problem by software solutions, you must ensure that functionality is possible at the physical level.

First, we try to connect the USB plug of the device to other connectors on the computer; if the system still does not recognize the equipment, then you should check its serviceability on another PC or laptop. It is also necessary to inspect and clean all plug contacts and connectors.

If necessary actions produced, but Windows 10 does not read the data and continues to display error code 43, you need to check the status of the drivers.

Checking and updating drivers

Often the problem with the system recognizing a USB connection lies in the drivers. First, you need to update your drivers in Windows 10 Device Manager.

right-click on the name, in the pop-up menu click “Update drivers”;
search for drivers on your computer, select from the list of already installed ones;
most often there is only one driver in the list, but if there are several, you need to select the first one, click the “Next” button and wait for installation.

If the actions taken are successful, the system should detect unidentified connection, then you will see its name in the list. But if not, then you need to try another option for updating drivers, download them from a disk or download drivers compatible with Windows 10 from the official website. You should also check and update the drivers for your computer's chipset. Use your hardware manufacturer's website to find and download new drivers that match your operating system.

Checking power consumption and relieving static electricity

In the properties of the “USB Root Hub” on the “Power” tab, make sure that the power consumption does not exceed the permissible value. If such a problem exists, you need to completely turn off the computer:

After starting the operating system, the problem should be resolved.

Setting Energy Saver

Descriptor request failure (code 43) can also appear with some frequency, then there is a possibility that the connectors become de-energized after some time.

Go to "Device Manager" and in the "Controllers" section open the properties of these objects: "Generic USB Hub", "Root Hub", "Multiple Device" . If you see that the power saving function is enabled on the Power Management tab, uncheck the box next to this item.

If none of the solutions solved the problem and Windows 10 still displays an error, check USB functionality in the base BIOS. Can be used for this purpose installation flash drive. The USB hub may be disabled in the system settings. If enabling the function does not help you see the flash drive, you can update the BIOS.

Do not rush to write off the connected devices, motherboard or computer connectors and take everything for repair. Of course, sometimes there is such a possibility, but these are already extreme measures and in most cases the problem is solved by one of the methods listed above.

When connecting any third party device to personal computer with Windows 10 (as well as Windows 8), for example USB, the system may not recognize the device, it’s no secret. One of this type of errors is error 43. It signals a problem with gaining access to USB directly. The display will indicate that an unknown device is connected, and a “Device Descriptor Request Failed” notification will appear. The error is not fatal; it can be corrected in several ways. However, the essence may also lie in problems with software: drivers, distribution of energy savings, and maybe not only.

Before looking for new drivers, check two things: quality USB port and quality of work with peripherals (laptops, tablets, etc.). If the port is subject to severe damage and/or oxidation, this is likely the root of the problem. If not, then most likely it is software. In any case, the error can be resolved in several ways.

Installing new drivers

There's a chance that the drivers you've had for a long time are no longer compatible with your PC, are outdated, or need updating. This can cause malfunctions. To correct the situation this way, you need to do the following.

In Device Manager (keys « Pusk" +R) write devmgmt.msc.

then in the window that appears, click on « TOUSB controllers".

Right-click on the device and select « ABOUTupdate drivers".
Click « INsearch for drivers".
Click on « INselect from the list of installed drivers."
A list should appear with the only compatible driver, select it and click "Further".

After performing this operation at all three points, the error should be eliminated. If not, then the problem lies in the power supply.

Power or static electricity problems

Often an error can be neutralized in a slightly extravagant, but time-tested way - turning off and on the computer. This path requires not just restarting the computer, but this is what you need to do:

Power supply

If the previous method did not help, or the problem returned after a while, try disabling the power saving function of the USB device.

To do this, you need to go to the same directory as in the case of drivers, but now go to « WITHtroops" all three devices. IN « WITHtroops" find the item « Upower management", and then uncheck the box next to the option « RAllow this device to turn off to save power".

Problems on laptops

Let's look at solving the problem on laptops.

Power supply

If you use a laptop, then this may be suitable for you. Some laptops have a function to turn off the power supply to ports that have not been used for a long time. Most often this happens with the ill-fated USB 3.0. It is enough to disable this function. To do this you need to go to the section « Epower supply" V « Pcontrol panels". Then you need to select the power plan for your laptop and then go to "Setting up the power plan". In the tab « Ptemporary shutdown parameterUSBport” In chapter « PparametersUSB» switch from « Rallowed" on « Zprohibited". Save your changes.

Drivers

And again, if you have a laptop. Maybe you just don't have official drivers on the motherboard or chipset. You need to get them from the official website of your laptop manufacturer, then it’s better to immediately download all the drivers that you may not have. Don't underestimate the seriousness of this point. If neither reconfiguring the power supply nor updating the drivers helped you, it is possible that you actually do not have compatible basic software, and you should definitely download it. Most often, chipset drivers are called something like this: « ACPI_Driver», « Intel_ManagementEngine_Interface» . .

If all else fails

If none of the above helped your grief, then you are missing something, or you have a broken USB, try something else. Well, then only fixing the BIOS, but for this you need professional and direct hands, otherwise you may never turn on your computer again. But it's better to buy new usb. In any case, you can always call/write to a computer technician if no article on the Internet could help you.
