Unknown Device - what is it and how to fix the error? Unknown Device what is it and how to fix it I inserted a flash drive and it showed error code 43

Code 43 is the most common error in Device Manager. This error can appear in all operating systems, including the latest modifications of Windows. The reason why error code 43 appears is that the device manager is stopping the device due to an unspecified hardware related error. using Windows(drivers).

Possible solutions

There are several options to correct such errors in operation.

  1. Restart your computer. Perhaps this action will be the most effective, since often such a problem is caused by a temporary problem with the equipment. Sometimes one reboot is not enough and the computer has to be completely disconnected from the network. In the case of a laptop, you need to turn it off, remove the battery and wait a couple of minutes. After this you can turn it on again.
  2. If you change any settings in the Task Manager, if they lead to error 43, you must cancel them and restart the computer. The same should be done when installing the device.
  3. Also, this error can be fixed by updating the driver. This may solve the problem if the drivers were previously installed incorrectly or damaged.
  4. Another way to resolve this error is to install a Windows update package. Thus, the update package may contain exactly those files that are necessary to resolve error 43.
  5. The solution to the problem may be given in the troubleshooting guide for the hardware device.
  6. The last resort solution is to replace the device itself, since this may be the problem. It simply may not be compatible with the operating system on your computer.

You should not count on serious reasons for the occurrence of 43 errors for bluetooth devices; most likely the solution will be simple steps.

Other Possible Causes

There are other reasons why code 43 appears on the monitor screen. For example, it may be caused by the removal or modification of software that was associated with the operating system. In addition, Device Manager may show code 43 not only if the drivers are damaged, but also if they are out of date. They may also be damaged by a virus or malware. Another common cause of code 43 is a driver conflict that occurs after installing new hardware.

In addition, the equipment may simply be faulty. Often in Windows 7 this problem occurs after the system is put into Sleep Mode. IN in this case should be guided by specially created Windows developers instructions. However, it should be remembered that the actions specified in the instructions must be performed only when this problem appears after exiting the “Hibernation Mode” of Windows 7.

To get rid of this problem, you can also try the following:

  1. Recovering registry entries that were associated with a similar error
  2. Search and remove viruses and malware.
  3. Completely clean your computer of unnecessary and temporary files. For these purposes, you can use the numerous programs available for free on the Internet.
  4. Activate System File Checker
  5. Installing all kinds of updates
  6. Finding errors on your hard drive
  7. Finding errors in RAM

You can watch the video instructions in English on how to fix error 43:

A number of Windows OS users may encounter error code 43, which causes the window of a running program to simply crash. You may also encounter the error “This device has been stopped because it reported a problem code 43” in a situation where one of the devices connected to the system (for example, a video card) is displayed in the Device Manager with the status “stopped”. In this material, I will tell you what error 43 “this device has stopped” is, what the reasons for its occurrence are, and I will also tell you how to fix error 43 on your PCs.

Error "This device has been stopped 43"

The essence and causes of error code 43

Typically, error 43 manifests itself with system messages “Code 43”, “This device has been stopped because it has reported problems,” “Windows has stopped this device because it has reported problems.(Code 43)” and a number of other analogues. A computer with this error may freeze for several seconds, often slows down when working with the keyboard and mouse, and generally behaves quite unstable.


This problem usually occurs in a situation where Device Manager stops a device due to problems with the device, or when it does not recognize a certain device at all ( hard drive, video card, external USB device and so on).

The mentioned dysfunctions can be caused by the following reasons:

How to Fix "This device has been stopped because it reported a problem code 43"

So how to fix error 43 on your computer? I recommend doing the following:

  1. Turn off and then turn on your PC. We need not just a reboot, but a complete shutdown of your computer in the standard way (after turning off, I recommend that you completely remove the power cord of your PC from the outlet for a minute, and then plug it back in; for laptop users, it will be important to remove the battery from your laptop for a minute). It is especially important to completely turn off the computer if error 43 appears associated with an external USB device;
  2. Reinstall the drivers for the problematic device. Click on the Start button, type devmgmt.msc in the search bar and press enter. Find the problematic device (usually indicated by an exclamation mark), right-click on it and select “Update driver” in the menu that appears.

It will also be relevant to go to the website of the manufacturer of your problematic device and download the latest drivers for it from there.

Plus, you can use the functionality special programs to update drivers (level DriverPack Solution) to install the latest drivers for your devices, this may help in the question of how to fix error 43 on your computer.

  • Uninstall and then reinstall the problematic device in Device Manager. Go to Device Manager as described above, find the problematic device, right-click on it and select “Delete” (if error 43 is observed with a USB device, delete each device under the “USB Controllers” (Universal Serial Bus) category).

Then click on the “Action” tab at the top, and select “Update hardware configuration” there. The system will look for the devices you removed and reinstall the drivers for them.

  • If the error “This device has stopped because it has reported a problem code 43” appears after installing a new device, then remove the new device from the system, restart the computer, and then check your PC for error 43. If there is a device conflict, try looking for other drivers to a recently installed conflicting device (use newer or older versions);
  • Check your system for viruses (Dr.Web CureIt!, Malware-Antimalware and a number of other programs will help);
  • Check your OS registry using special programs (CCleaner, RegCleaner and a number of others);


Conclusion

The main cause of error 43 “This device has been stopped” is a problem with the drivers of a certain device, as a result of which the latter ceases to function normally, forcing the system to suspend its operation. In this case, it is recommended to update the driver for the device by downloading the latest one from the manufacturer’s website, and if this does not help, follow the entire list of tips mentioned above, this will help fix error code 43 on your PC.

None of us are immune from the fact that at one point the Windows 10 operating system will display a video card error with code 43 on your laptop or computer. Moreover, this usually does not depend on the model and manufacturer - a failure can occur on both an NVidia and AMD Radeon video card. In this case, in the system device manager, an icon in the form of a yellow triangle with an exclamation mark will be displayed on the video adapter, and the following will be written in the device properties:
"This device has been stopped because it has reported a problem (Code 43)."

In the English version the error looks like this:
“Windows has stopped this device because it has reported problems. (Code 43)".

The reasons for the occurrence of such a situation can be several factors: a short-term failure of work operating system Windows 10, garbage or broken registry keys, problems with the device driver and even a possible conflict with RAM.

How to resolve device problem code 43

Step 1. To eliminate the usual simple failure of the Windows 10 OS, which also happens, you first need to simply turn off your computer or laptop, and then unplug the power cord from the outlet. If you have a laptop, disconnect the battery. After 15 minutes, connect everything again and turn on the device. Didn't help and error 43 appears again on AMD or NVidia? We are trying to restore order in the system.

Step 2. Let's try to clean the Windows 10 registry from various junk that often causes its operation to malfunction. And the excellent CCleaner utility will help us in this difficult work. For our purposes, its free FREE version is quite suitable.

Launch the utility and open the “Registry” section. First, we launch the analysis by clicking the “Search for Problems” button. We wait until the analysis is completed and all found problems are shown. Click on the “Fix” button. After this, we reboot and check whether the problem Code 43 was resolved or not.

Step 3. Windows rollback. Another method that often helps out in case of various problems in Windows 10 is to restore the system to the previous one, when the video adapter worked without problems.

Step 4. Reinstalling and updating the video card driver. Do not forget that the video card driver could also become corrupted and begin to fail, and therefore it is worth trying to update it to the most latest version. You can download drivers for NVidia, for AMD Radeon -. Download the installation package and run it.
If suddenly the software does not install automatically, we will try to update manually. To do this, open the Windows Device Manager and find the “Video Adapters” section:

Right-click on your Nvidia, AMD Radeon or other video card and select “Update drivers” from the menu that opens. Now you need to specify the path to the device driver, after which it will be updated.

Step 5. The cause of problems with code 43 on the video card may be that there is not enough RAM. Often this trick helps solve this issue! You need to open the Windows Control Panel and go to the “System and Security” >> “Administration” section.
In the window that opens, double-click on the “System Configuration” item to open the following window:

Here you need to go to the “Download” tab and the “Advanced options” button.

Another window will appear in which you need to check the “Maximum memory” box and click on the “OK” button.
Reboot the computer or laptop again and check whether the video driver issues error 43 or not.

Step 6. The last option that can help fix the device problem is shamanism with RAM.
Turn off the power system unit and unscrew the lid. We pull out all the memory sticks except one. The main thing is that it should be no more than 2 GB in size.

Turn on the PC and check. Has the problem code 43 of the video card disappeared? Turn off the computer again, add another bar and check. if the error disappears, turn off the computer and add more, and so on until the error appears again. The problem is most likely in the last module inserted. To be sure, pull out the one that turned on first and look at the result.

P.S.: If none of the proposed methods help, then the cause is most likely a broken video card and you need to send it for diagnostics. At least try turning it on with friends or relatives and check there.

This is probably one of the most annoying and common error codes that windows can report. Well, error 43 should also be classified as universal, because it is associated with any computer hardware devices, and they, in turn, may not work. Error code 43 indicates the following are not recognized: USB ports, hard drive, video card or any other equipment connected to the computer.

Typically, the error message contains the following text: "The device has stopped because it reported problems. (Code 43)."

If you open “Device Manager” and view the properties of the equipment that received this error, then in the “General” section you will see the following picture: The hardware device shown in this screenshot is just an example. Error 43 can appear on any device connected to your computer.

Reasons for error 43

In 90% of cases, error code 43 is associated with device drivers, which in turn can be damaged by the most in various ways(for example, viruses). In the remaining 10%, the hardware device has failed and requires replacement or repair.

Sometimes this error can be solved by simply restarting the computer, cleaning the registry (using specialized software) or “rolling back” (restoring) Windows 7, 8 or 10. But believe me, this will only help temporarily - literally in a day, week or month error code 43 will come back again.

Fixing error code 43

First way
If you don’t want to bother uninstalling and reinstalling newer versions of drivers yourself, then I recommend using specialized software that will do all the work for you. Such programs are capable of automatically finding drivers for the devices you specify and installing them without your intervention. This method is absolutely safe and will save your time. Among best programs, For automatic update drivers, I would highlight the following:
  • DriverPack Solution
  • Driver Booster
  • Device Doctor
  • Driver Genius
Second way
This method is suitable for more advanced computer users. Yes, and it is much more interesting, because you will need to delve a little into the system. So, to fix error code 43 manually you need to:

1. Remove the current driver:

Launch the “Run” dialog box using the “Start” menu or using the Win+R key combination.

In the open line, enter the following phrase sysdm.cpl and press OK or the Enter button.


The System Properties dialog box opens. Go to the “Hardware” tab and click on the “Device Manager” button. A new Device Manager dialog box will open. Among the available devices, we find the one that Windows signals with error code 43. Right-click on it and select “Properties” in the context menu that appears. Next, in the properties window, open the “Driver” tab and click the “Delete” button (located at the very bottom).

2. Find a new driver

After you remove the old driver, you need to find a similar one, only a newer one. To do this, you can visit the device manufacturer’s website and look on its pages for a special section where the drivers themselves are located. 3. Download the driver Download the driver and save it to your computer. Most likely it will be a compressed .exe ZIP file or RAR archivers.

4. Install the driver

Unzip the downloaded .zip (or .rar) file and run the installer.

5. Reboot the computer

If you removed the old device driver and installed a new one in its place, this should solve your problem of communication between the operating system and the hardware. Otherwise, I recommend that you remove the faulty device from your computer and try connecting it to another PC to test if it works properly. By resorting to this method, you may save money and simply try to look for new drivers or even reinstall the operating system.

If on the other windows computer displays error 43, then there is nothing to be done - you will have to purchase a replacement for the damaged device.

Problem: code 43 device error - how to fix it?

Recently I was dealing with an interesting problem - a friend of mine encountered a problem with code 43 while reinstalling the system on an NVidia video adapter. To fix the error, he tried to reinstall the driver from the disk. After that, I reinstalled Windows 10 again. This did not bring any results. I rolled back to Windows 7. In general, I tried as hard as I could, but nothing worked. With this, he brought the system unit to me. Looking ahead, I will say that I managed to figure out the reasons for the video card error code 43 and everything turned out to be sad. But let's talk about everything in order. Let me start by saying that the most common cause of this problem is a problem with the device driver. By the way, it is most often observed on video cards. Although this is not surprising - among amateurs computer games No driver in the system is updated as often as that of the video card. Sooner or later, the installation may fail, and the result will be exclamation mark icon in Device Manager. In such circumstances, the following can help. 1. Download the full set of software for your device from the manufacturer’s official website. In the case of NVidia video cards, this is WHQL, for Radeons - AMD Catalist Video Card Drivers. For other devices, do the same. 2. Remove the old video card driver in Device Manager.

3. Completely remove the accompanying software (NVIDIA Control Panel or AMD Catalyst Software) in “Control Panel” -> “Programs and Features”. 4. Clean the registry using some specialized utility. I prefer the all-in-one program CCLeaner.

5. Reboot the computer 6. Install the driver and software that you downloaded earlier and reboot again. After all this, the “device code 43” error should be eliminated.

In my case it was not a matter of software and I continued to dig further. For test purposes, I moved the video adapter to a known-good computer and also received an exclamation point and a sentence - “The device reported a problem...”, etc. Regarding video cards, this can happen if the device overheats immediately. My test subject is a passively cooled Nvidia GeForce 6600GT from Palit. Its operating temperature is about 75-78 degrees Celsius, in games it can heat up to 120. For 7 years, no one has ever changed the thermal paste on it. We take it apart and see - exactly, there is a piece of solid substance on the chip. Wipe it off with alcohol and apply a layer of new thermal paste.

Then we carefully put everything back together and check the operation of the device. Unfortunately, a miracle did not happen for me - the “Code 43” error did not go away. Apparently, before this, the video camera worked for a long time in extreme temperature conditions and the contacts or the chip itself were damaged. The only thing left to try is warming it up with a special hairdryer at the service center. I sent my friend there. If they charge you inexpensively, then good, but if they ask for a higher price, then it will be easier to buy a new video card. True, I know of cases where some craftsmen managed to fry it in the oven and the board even worked after that. But I'm not interested in such methods.

P.S. There is a scenario where, when connecting a flash drive, printer or something else via USB, the error “Unknown Device code 43” appears with the text: “launch is impossible, device descriptor request failed.” In the vast majority of cases, the cause is a low-quality cable or USB extension cable, replacing which completely eliminates the problem. It also often helps to simply switch the connector to an adjacent free USB port on motherboard. In addition, remember that you can always check the device’s functionality by connecting it to friends or acquaintances.

How to resolve error code 43 when connecting USB devices

Using the USB standard is one of the most common methods of exchanging data between devices. Its main advantage is its versatility, because USB is supported by almost all operating systems, including their oldest versions. A USB device connected to a computer is usually automatically recognized by the operating system, but in some cases errors occur due to various reasons. Thus, among the most common connection problems, error 43 can be noted.

Users may encounter it when connecting a variety of USB devices to their computer. The problem is that the computer does not see the USB device - it is inaccessible through Explorer, and in the Device Manager it is defined as unidentified. In the properties, you can see the description “device descriptor request failed” with code 43. Often the error is caused by hardware problems, but software failures also cannot be ruled out. Today we will look at the most common causes of error code 43 usb and learn how to fix it in Windows 7/10.

Physical damage to the port

Essentially, a handle failure indicates that the USB-connected device is not making proper contact with motherboard, so if USB does not see the device, the first thing you need to do is check the port itself for physical damage. Make sure that all contacts and wires of the connector are intact and have no signs of oxidation, but before that, try connecting the USB device to a different port. If it works fine, most likely the problem lies in a specific connector. In this case, you may need to replace the port.

Temporary equipment problems

Error code 43 may be caused by temporary hardware problems. To eliminate them, turn off your computer completely by unplugging the power cable. If it is a laptop, you must remove the battery after turning it off. After a few minutes, turn on the PC and check the ports. If the error was caused by temporary problems, after turning on the computer, all connectors should work normally.

Using USB Power Saving Mode

If you have power saving mode enabled, error 43 may occur due to insufficient power supply. You can check and fix it this way. Through the Start menu, open Device Manager, expand the “USB Controllers” branch and do the following for all devices in it. Right-click, open via context menu properties.

On the “Power Management” tab, uncheck the “Allow the computer to turn off this device to save power” checkbox.

Incorrect USB drivers

Incorrectly working drivers are quite capable of causing the error described above. The best solution in this case would be to reinstall them. As in the previous example, open Device Manager, expand the “USB Controllers” branch, right-click on the first device to bring up the menu and select the “Update Drivers” option.

In the window that opens, click “Search for drivers on your computer.”

Select a search option from already installed drivers.

When the driver appears in the window, install it again by selecting it with the mouse and clicking “Next”.

Similar steps must be repeated for all devices in the “USB Controllers” section.

Problems with motherboard drivers

We also cannot rule out problems with the chipset drivers. For some models of computers and laptops, those drivers that are installed from windows distribution, it may not be enough for the ports to work normally; they need “native” drivers. In this case, you can eliminate USB error code 43 by downloading and installing the correct drivers from the official website of the computer manufacturer. In particular, these include the Intel Chipset Driver, ACPI Driver and Intel Management Engine Interface.

Registry errors

In some cases, accumulated incorrect entries in the registry can cause the usb unknown device error. The solution is to clean it. For these purposes, you can use any more or less popular registry cleaner, such as CCleaner or Wise Registry Cleaner.

There is no guarantee that this will give a positive result, but in any case, cleaning the registry of outdated entries will not hurt.

Other reasons for error 43

Above, we looked at what most often causes error code 43 usb and how to fix it, but for the sake of completeness, we will also indicate other, not so common reasons. Avoid damage to system files. Launching command line As an administrator, run the command sfc /scannow.

If corrupted files are detected on the system, a corresponding notification will be displayed in the console.

If Windows 7/10 does not see the USB device due to some temporary problems, in the Device Manager, in the “USB Controllers” section, you can sequentially remove all devices, and then click “Update hardware configuration” in the main menu.

Make sure the device itself is in good condition and undamaged. The easiest way to do this is by connecting it to another PC. If your computer is old, the problem may be caused by outdated version BIOS. This scenario is unlikely, but it cannot be ruled out.

The occurrence of error 43 was noted when using regular or low-quality USB hubs on laptop computers. Not all models of laptops and netbooks are capable of providing a device connected via an adapter with sufficient energy, so in such cases it is better to use self-powered USB hubs.

And one last thing. If the error began to appear after a system crash, installation of some third-party program or PC configuration changes, try rolling back to a previous restore point, this may solve your problem.

Unknown Device (code 43): what is this error and how to fix it?

After reinstalling the operating system, you need to install drivers for all equipment. This ensures stable and fast work hardware. But there are times when, after unpacking the utilities, some devices are not identified and report an error: “this device has been stopped because it reported a problem (code 43).” Therefore, let's look at everything about Unknown Device: what it is and how to fix it.

What is Unknown Device?

An Unknown Device is a device connected to a computer for which the drivers are not installed or are damaged. This could be a video card, audio chip, or connection ports. Moreover, in some cases the device can work despite the occurrence of an error, albeit slowly and unstable.

Some don't pay attention this problem. But if the unknown device is a video card, you will not be able to play demanding games; if the WiFi module is used, you will lose wireless internet, and if you have an audio chip, get ready to listen to music only on your phone. Therefore, it is imperative to identify the computer component and fix the problem.

Causes

It all depends on several factors. Let's look at all possible prerequisites for the error:

  • incompatibility of drivers and OS;
  • infection of the system with viruses;
  • unfaithful BIOS settings;
  • corruption of driver files due to system errors;
  • physical damage to the device or connection cable.

Fixes

There are many life hacks to restore the device to working condition. But not every method will be equally effective in your situation. Therefore, we will divide the methods into two groups and sort them by probability of occurrence.

Basic methods

In 80% of cases, the instructions below fix the unknown device error.

Driver installation

If you recently reinstalled Windows and the standard drivers do not fit one of your devices, you should consider a separate installation. To do this:

Attention! Download files only from the official websites of the equipment manufacturer! Alternatively, use the trusted DriverPack Solution app.

If your system is not new and you have not seen Unknown Device before, then:

  1. Go to “This PC” – “System Properties” – “Device Manager”.
  2. Find Unknown Device, open Properties and click the Roll Back button.

Reverting to the previous hardware configuration may solve the problem. If unsuccessful, remove the driver and repeat the instructions from the previous subheading.

Unknown Device: how to fix

There are many life hacks to restore the device to working condition. But not every method will be equally effective in your situation. Therefore, we will divide the methods into two groups and sort them by probability of occurrence.

Advice! First, check whether the device works on other computers in order to exclude “dancing with a tambourine” in case of a malfunction of the device itself.

Basic methods

In 80% of cases, the instructions below fix the unknown device error.

Driver installation

If you recently reinstalled Windows and the standard drivers do not work for one of your devices, you should consider a separate installation. To do this:

Roll back to the previous driver or remove it

If your system is not new and you have not seen Unknown Device before, then:

  1. Go to “This PC” – “System Properties” – “Device Manager”.
  2. Find Unknown Device, open Properties and click the Roll Back button.

Reverting to the previous hardware configuration may solve the problem. If unsuccessful, remove the driver and repeat the instructions from the previous subheading.

Virus scan

Malicious programs can damage or delete system files, including drivers. Therefore, Unknown Device may be the most harmless consequence imaginable. For Windows checks need to:

If no viruses were found or removing them did not solve the problem with Unknown Device, proceed to alternative methods.

Alternative methods

The methods described below help solve the problem in exceptional situations.

Installing system updates

Automatically updated drivers are a very good thing. But along with this, Windows Update must also work, because Sometimes there is a version conflict leading to crashes.

To do this, go to “Control Panel” – “Windows Update” and turn on automatic search and installation of updates from Microsoft.

Using a USB hub

If it turns out that Unknown Device appears when USB connection devices, you should think about buying a USB hub with separate power supply. The fact is that for modern mobile devices(portable hard drives, 3G modems, WiFi modules etc.) requires more power than conventional flash drives. Outdated models of laptops, netbooks and even computers do not have the required output current and/or voltage.

System cleaning

Cluster system garbage and incorrect keys in the registry negatively affect the operation of the computer. A symptom of this is also the appearance of Unknown Device.

To clean the system you need:

Replacing connection cables and cables

Poor contact, broken wires and cables, burnt-out cables, or simple dust contamination can cause problems with “identifying” the device. Check the USB connectors and do a “spring cleaning” inside the laptop or computer system unit. Pay special attention to the motherboard.

Attention! If you lack experience, do not disassemble the computer yourself; you may damage it.

BIOS update and setup

In exceptional situations, “code 43” is caused by incorrect settings or outdated BIOS version. Perhaps you have one of the connectors on the motherboard software disabled or set to automatic mode enable, which results in Unknown Device.

To update the basic I/O system, see this article.

If none of the methods helped you, write in the comments, we will try to fix it together. After all, an error such as Unknown Device can be resolved independently, without contacting a service center.
