Find an unknown Windows 7 device. How to find drivers for unknown devices in device manager. If nothing is displayed

When setting the "seven", users are very often faced with the fact that a notification or a message arises in the system tray that the unknown to many users seem to be some kind of virus. Maybe so, but in general, the situation is much easier.

Unknown device in Windows 7 Device Manager: What is it?

Let's start with the fact that no Windows system, no matter how much her developers, can not have in its standard package Installation of absolutely all drivers and absolutely for all devices. In other words, we see the code in Windows 7 device manager, it can only mean that it is as such in terms of "iron" on the computer is present, and it cannot work normally.

And what is this device? As a rule, these are the most standard USB carriers, and simply speaking, flash drives or removable hard drives, as well as MIDI keyboards without installed drivers. Firstly, file Systems When connecting a removable device or even a mobile gadget may not coincide. Secondly, computer system It can automatically request its formatting.

Well, if it really is connected with the flash drive. And then the problem is that the user will detect an unknown device in the dispatcher windows tasks 7 may have other root causes. According to many users, the problem consists only in the irrelevance of the drivers. This is not true. So "smart" specialists want to advise apply standard method Unknown device from the system database. Nothing it does not work, but "Windows" writes that the most appropriate driver is installed.

You will have to either download drivers manually, or put an automatic client. One of these is software package Driver Booster. Note, the third updated version is installed on the computer completely free and updates the drivers to automatic mode Not one, as it was in the previous variations, but completely and immediately.

How to go to Windows 7 Device Manager and what to do next?

Regarding the service entry that allows you to view all the devices, they work or not, you can mark the universal dispatcher, although not every user knows that it is possible to turn off or activate any device in terms of "iron" in the BIOS. If the component is disabled, it will not even see it when configuring it.

Nevertheless, we will analyze the question of how to enter this service and why in front of the user sometimes there is an empty Windows 7 device manager. First, you need to use the "Run" menu, and do not wander through all sorts of control panels and enter the devmgmt.msc command there which is in the rapid version and provides access to this service.

It follows from the view menu to select exactly what is required. If nothing helps, you need to use the service system called by the Services.msc command.

If nothing is displayed

Now go to the sick question. And what if there is not a single device in the manager at all, although the user knows that they are and work (or worked until certain time)?

First, it is worth checking the system for viruses (this is not discussed). Secondly, whether this is a USB media that is not supported by Microsoft or the BIOS boot system.

Here you really have to put specific drivers. By the way, the owners of "steep" suffer from such situations as it seems to them, video cards. In fact, an unknown device in the Windows 7 devices manager (and not only) can be displayed for only the reason that the system itself is outdated. Here you just need to turn on auto update. And even even an update of the system does not always work correctly. Drivers of devices that are not in the list of directory of the installation "Windows" simply will not be installed.

Therefore, it is recommended to use exclusively "native" drives with drivers or programs like Ultimate Driver Solution or Driver Booster. By the way, the last one, the third version is absolutely free and updates the drivers not one as it was provided before, but all at once.

What is the result?

Finally, it remains to add that the problem is that somewhere and somehow the unknown device will be detected or shown in the Windows 7 task manager, at least a simple installation of the appropriate driver, if not from the Windows directory, then from the "native" or update - Yes sir.

Naturally, it is worth saying that to update the desired drivers designed for any "Windows" is not worth it. All the same, the system will try to establish something from its catalog, considering them the most correct. There are many complaints about this. Just try to disable the update of the M system update to use the above-mentioned program. The difference is colossal.

If you saw the notification "Unknown Device" in the Windows 7 Device Manager, find the appropriate driver for it will not be easy. After all, there is not specified necessary information: Device model, its manufacturer and so on. A similar problem may occur if the system has determined the assignment of the gadget, but did not find a suitable software for it. Then the error "Code 28" appears. The equipment will be displayed in the Manager. But you will not be able to use it.

If you recently discovered this problem, check the boards and the periphery that connected to lately. So you find all the necessary utilities on the Internet. Or install them from the disk. But in most cases it is impossible to determine the unknown device "method of scientific tick", alternately connecting and disconnecting different gadgets and fees. There are several ways to get rid of the message "Code 28".

  1. Go to the "Control Panel".
  2. If you have an active viewing option "Icons", just find the dispatcher. There all menus are located alphabetically.
  3. If you are displayed in categories, then go to the "Equipment and Sound". In the subcategory "Devices and Printers" will be the necessary item. To start it, you need to activate admin rights.
  4. If there is an unknown equipment in it, next to it will be an exclamation mark in the yellow triangle.

In Windows 8 and 8.1, this can be done like this:

  1. Click right-click Mice on the "Start" menu. It is with Windows Logo.
  2. Select "Device Manager" ("Device Manager").

More couple of ways.

  1. Right-click on the "My Computer" icon.
  2. Item "Management".
  3. In the hierarchy " Service Programs"Will be what you need.

And the last option.

  1. Go to Start - Run. Or press Win + R keys.
  2. In the Input field, write "Devmgmt.msc" (without quotes).
  3. Click OK.

To find in the Dispatcher unidentified devices or errors "Code 28", you will not need to turn all lists alternately. The category in which there is a "problem" equipment is opened in advance. And next to it will be the corresponding icon.

Simple ways

Before you search for a driver, try the worst:

  • Restart the computer.
  • Right-click on any free location of the dispatcher window (where there are no buttons and names). Select "Update Configuration".
  • Disconnect and connect the device again, which has not defined the system.
  • Download all topical updates for Windows.
  • Use the utility for the mass update. It automatically analyzes all the equipment and suggest "fresh" software versions. Suitable, for example, driver programs Booster, Driver Easy, Driver Updater. And they are similar. They can find outdated driver And put a new one instead.

It also makes sense to try the New Device Settings Wizard:

  1. Go to the control panel.
  2. Turn on the display by category (if it is inactive). To do this, click on the "View" link to the top and select the option you want.
  3. Open "Equipment and Sound".
  4. Click "Adding Devices".
  5. Windows will begin searching for new equipment.

If nothing helped, and a yellow icon is still displayed in the list, you need to find the driver yourself.

Via device ID

When you know the gadget model, the software is easy enough to search for it. You can go to the manufacturer's website and roll out from there updates. But if you have no information about the device, or you do not know which item gives an error "Code 28", the task is slightly complicated. You can not install all drivers on the PC that there is online. Therefore, you need to know the identifier.

  1. In the Windows Manager, right-click on an unknown device.
  2. Item "Properties".
  3. Tab "Information".
  4. In the "Property" drop-down list, select Education IDs, "Instance ID" or "ID".
  5. There will be an identifier of an indefinite device. It looks like this: "USB \\ Vid_8087 & Pid_0024 & Rev_0000" or "PCI \\ VEN_8086 ° CC_11E31 & CC_0C0330". You can find the driver.
  6. In fact, you do not need everything ID. Only certain values. Figures after "VID" or "VEN" denote the manufacturer. And "PID" or "DEV" is a gadget model.
  7. Before a slash ("oblique line"), the port is specified to which the equipment is connected.
  8. In some gadgets, identifiers look different.
  9. Open any search engine.
  10. Copy the ID into it and start the search. The results will be the model, and the manufacturer, and the appropriate software.

Here is how to find a driver for an unknown device if you do not want to use search engines:

  • Site devid.info. Insert in the Gadget ID field and you can choose software.
  • Service pcidatabase.com. In the VENDOR SEARCH line, type the manufacturer's number (specified in the device ID after "VID" or "VEN"). In Device Search, the model identifier (written after "PID" or "DEV"). Click on the second "Search" button. Several options may appear. Select one in which the model and the manufacturer coincide with your ID. Description of equipment. The "Notes" field will be a link to software.

Code 28.

If an error "Code 28" appears, the unknown device will not be able to work. It pops up if there is no suitable software for the device. Sometimes it happens after reinstalling Windows, scale update or connection of new equipment. To remove the error, download the appropriate drivers. They can be found on the output of the gadget. The process is described in detail in the previous chapter.

If an error with 28 code appeared on the "famous" device, it is possible to correct it directly in the controller.

  1. Open it.
  2. Right-click on the device model, which caused a failure.
  3. Select "Properties".
  4. Section "Driver".
  5. "Update" button.
  6. The system will launch a search through windows Center Update.

Click update - and reinstall automatically

You can also try to delete software to set it again. It should be done only if you already have suitable utilities for equipment. In no case can not be erased by programs that belong to important resources Computer. If you remove, for example, the video card utilities, it will turn off.

In some cases, the message "Code 28" appears precisely because of the new versions of software. If they work unstable or incompatible specifically with your equipment. Then you need to return the previous drivers. This can be done in the same menu. But instead of "update", click the button "Run".

If the software is still not suitable, try installing it in compatibility mode with previous versions OS.

  1. Click on the installer with the right mouse button.
  2. Item "Properties".
  3. Compatibility tab.
  4. Tick \u200b\u200bthe corresponding item and select Windows from the list.
  5. It is impossible to say exactly what software system will definitely work. Therefore, you have to try different options.

Programs

The driver for an unknown device Windows 7 can be found using the Unknown Device Identifier program. She "sees" equipment that is not identified in the system. The utility issues full list Boards and devices that are connected to PCs.

The application looks like a task manager. Therefore, it is easy to navigate. But there is no support for the Russian language yet.

To exit the site with the drivers, click on the name of the model right-click and click on the "Find Driver". To save the equipment in the file, in context menu Select "Save to File".

If an unknown device appeared in the manager, you can find software for it by id. There are also specialized programs for downloading suitable drivers and identification of gadgets.

1. How to go to the Device Manager:

Windows XP.: on the desktop or in the Start menu, click on my computer right clawing mouse \u003d\u003e Control \u003d\u003e Device Manager

Start \u003d\u003e Settings \u003d\u003e Control Panel \u003d\u003e System Properties \u003d\u003e Equipment \u003d\u003e Device Manager

Windows 7: In the start or on the desktop, click on the computer right mouse button \u003d\u003e Control

Device Manager

Start \u003d\u003e In the search string, enter the device manager and open it

Windows 8:

Press windows keys + C \u003d\u003e Settings \u003d\u003e Device Manager

search \u003d\u003e Device Manager

IN Windows 8.1.click on the start in the lower left corner of the right mouse button \u003d\u003e Device Manager.

2. Installing devices If you have a drive with drivers:

Very often, a person who does not know how to put the drivers on the device - takes all the discs that he has and starts installing everything from them without parsing ... after which there is a lot of superfluous on the computer, a bad beginning for a new operating system ... Drivers disconnect It comes in a set when buying a computer (laptop), and it is written on what operating systems it supports. Therefore, if it says that it supports Windows XP, and you are trying to install Windows 7 - then skip this item, and roll out new drivers from the Internet ..

The program data will be outlined almost always if you have no drives with drivers, and if you do not know the models of your device. You can download online versionwhich scanning the system and rolls out the necessary driversBut often network devices Not installed and the Internet is not. For this, download full version data of programs, write it to the disk, USB drive, or external hard drive and run on the computer.

Using SamDrivers, you can save the driver, install the drivers and the assembly includes a specific set. standard software. To install the drivers, press Driver Install: Driver Pack Solution Plus. In the list will offer update and install drivers on devices

At the top there are drivers and program bookmarks, you can choose which devices to install and update, and which programs are installed. Or click "Install and update", let him put everything. In the next window, you choose - put only drivers, or the programs also need.

We are waiting for some time, watch the pictures, and if everything is fine - there will be no unknown devices in the device manager, and there will be no yellow icons.

4. Installing drivers using the device model:

With laptops just easier than with a computer, and if you know the model of the laptop (it is often written below or under the battery), you can go to the manufacturer's website and pump out the drivers for all devices of this laptop. We go to the manufacturer's website, enter the model, driver and version of the operating system (version of the operating system can be viewed by clicking on the computer (my computer) with the right mouse button \u003d\u003e Properties \u003d\u003e System Properties will open):

All manufacturers will not list, if your model is not in the list - use the search, and find the official website of your device. Of course you can download and on other sites, but as practice shows - there is a malicious software in the load.

For PC users: you need to know the model of your motherboard, video cards and other connected devices. The model name can be viewed in the papers that you were given when buying a PC, or see the inscription on the devices themselves. To see the inscriptions - you need to remove the side cover

for example, judging from the inscription of the parent asus boards KBV-X SE

the video card can be built-in (integrated) and separate board (discrete). If the video card is integrated - then by setting all the drivers by the name of your motherboard, drivers will be installed and on the video, if discrete - then you need to look at its name, after which the drivers roll out from the Internet. In the picture, the name of the video card: GeForce FX5500

There is another way to find out the device model and not consider the name of the models under the lid - download the program Aida or Everest and see device names

after you find out the name of your device - go to the manufacturer's official website and download the driver for your operating system, or search for drivers in the search engine.

5. Installation of devices on the equipment code:

Each equipment has an identification code, just like people :). Therefore, if there are no unknown devices, if there is no drives with drivers, and if you do not know the model, let's look for the equipment ID:

  • go to the tab Details and in the list select Equipment ID

  • In the value field written a unique equipment ID

  • open a search engine and enter this ID there (you can copy it from the previous window by pressing the right mouse button - copy)

  • the list does not necessarily have a link to the driver, it may simply be a hint with the title of the device, and then by name you go and download the necessary drivers from the official site.

6. Installing drivers manually:

Frequency, but it happens that there is a folder with drivers on our computer or on a flash drive, and you need to specify the path to this folder when installing the device. To do this, go to the device manager, click on the desired device with the right mouse button \u003d\u003e Refresh Driver

In the window that appears, select "Perform the search for drivers on this computer"(or in Windows XP - set from the specified place)

Click the review and specify the path to the folder with the drivers, then click OK and wait until the device is installed

Also in Windows implemented installation of drivers automatically with windows updatesBut unfortunately in updates there are drivers not for each device. But still to check selected automatic installation Drivers S. Windows Update. or not:

  • We go into the start, in the search bar, enter the change settings \u003d\u003e Select the found


I hope you found your way to install the drivers, in any cases remember - the drivers are needed not only on the device in the PC itself (laptop), and on the devices that you connect. That is, if you connected the printer Samsung SCX. 4200 to this laptop - go to the official website of the Samsung and download the driver for it. If something is not clear, or there are suggestions - write comments :). Good luck to you!

It is no secret that in Windows-systems some "iron" and virtual devices may not only not work, but not to be determined at all. Therefore, when using the appropriate user control element and sees an unknown device in the "Device Manager" of Windows 7. Other systems from such problems are also not insured. But consider issues related to the establishment of the performance of any component based on the seventh version of the OS.

Why does an unknown device appear in the Windows 7 Device Manager?

As for the reasons for the fact that the system does not perceive the "iron" and the virtual component, the most important thing is that Windows simply cannot receive management due to the lack of an appropriate driver.

In some cases, it can establish how it seems to it, the most suitable driver, but this effect does not give. That is why there is an unknown device in the "Device Manager" of Windows 7, and even in the system tray after trying to install the driver pops up a notification that for detected (well, if so!) The devices could not install the control driver, because of which it and will not work.

Why is it going on, it is not difficult to understand. Drivers in the database simply not. And it looks very dubious that the Windows-systems developers could include in the distribution (even most complete) drivers for absolutely all devices known today. In addition, some specific devices like removable USB drives, memory cards or even sound cards Microsoft services are not supported at all. Even with an online search, the appeal primarily produces to servers of the system developer corporation, and not to the resources of equipment manufacturers.

How to open "Device Manager" in Windows 7?

Now a few words about the management section itself. The question of how to open the "Device Manager" in Windows 7, has several solutions.

The classic method is considered to be its call from the "Control Panel", in which, when displaying partitions to simplify the search, you need to install large or minor icons.

You can also simply gain access to this toolload from the management (administration) section, which is called through the PCM menu on the computer icon.

Finally, you can use the "Run" Console (Win + R), in which the DevmGMT.msc command is entered. In principle, all methods are quite simple, and the method of calling the control toolkit rather can be attributed solely to the question of preferences.

How to define an unknown or failure device?

Unknown device in the "Device Manager" of Windows 7 or any other modification of the operating system can be identified even visually. This component is marked with a yellow marker.

However, it may be absent in the list, so additional funds will have to view.

And additionally, you can use the system information about the system (MSINFO32), where the display of malfunction devices is selected. But usually such actions are not required and except that in cases where the device in the "Dispatcher" is not displayed in general (although it may not be here).

How to display hidden devices

Hidden devices in the Windows 7 Device Manager can be seen if you contact the corresponding view menu on the main panel from above.

When it is open, a string of displaying such objects is simply activated, after which the list will increase significantly (for example, a portable device section will appear).

Several examples of codes indicating the inoperability of devices

Now consider the few most common descriptions of iron errors or virtual components.

To begin with, you should pay attention to the unknown device in the "Device Manager" of Windows 7 (code 28), the description of which can be viewed in the Property section. It indicates that the device simply not installed drivers, or the system did not find previously saved control programs.

If you look at the unknown device in the Device Manager of Windows 7 (code 43), the problem of its recognition is mainly related to USB drives or external HDD.. The presence of this particular code speaks of problems with connecting when motherboard Cannot access the device through the appropriate port in the descriptor failures.

Search and installation methods for drivers

When describing the options for correction of the situation, we start with the devices with a description in the form of code 43.

Not to mention the installation or updating of the drivers, the most effective method is a ban on disabling the USB root housing to save energy. For set scheme reduced energy consumption This will give an instant effect.

But in most cases you will have to reinstall or update the drivers. If there installation disk with drivers, which, as a rule, comes with the purchase of a computer device or some equipment, when re-setting the system, you need to specify automatic search, and installation from the specified place ( optical media, flash drive or folder on your computer if the driver is saved on the hard disk). In the extreme case, you can use automatic driver search on Winchester.

No less simple method It is considered to use automated utilities, allowing you to easily define a device of any type, download a driver from the Internet, and it is from the resource of the equipment manufacturer, after which the Driver Pack Solution, Driver Booster, etc.). This technique looks preferable.

But if there is no such kind of program, you can download the installer from the Internet and yourself. But first, go to the properties menu of the problem component and on the information tab of the equipment ID, then select the longest code from the list, containing the VEN and DEV parameters, and set the search on the Internet precisely for these values. To do this, you can use either special sites or a manufacturer's resource (if known), or by the usual search using some service (Google, Yandex, etc.).

After that, it will only be left to download the installer on the computer and install the driver yourself. This may be an executable EXE format file, and an object with an INF extension, which you want to use the PCM menu (but for some files such actions are not provided).

conclusions

As you can see from all of the above, the problem of non-working or failure devices in any Windows system is a particular problem and is not. The main decision to correct the situation in most cases is reduced to the search and installation of the corresponding driver. How to do it? Here, as already mentioned above, the best use special third-party programsand not use the base microsoft data. As for specific (non-standard) devices, it can very well be that such automated utilities will not be able to help. therefore the best solution It will be the search for a manager driver on special identifiers.

If the user knows exactly what the device is connected, but is not determined at all, to begin with, it is necessary to check its activation in the BIOS parameter settings. If it is not there and there, to seek the causes of failures will be in the component itself (perhaps it does not work initially, has damage or factory defects). However, situations can be completely different. What is only problems with the supply of power supply to the "iron" component, if it is provided for its correct operation.

One of the private situations arising from work operating systems Windows 7 and Windows 8 is the case when the device manager appeared Unknown device. The reasons for this phenomenon may be several. Let's consider in detail the most frequent:

1) the new "net" Windows is installed;
This is the most popular case. Most often, users reinstalling windows simply forget that you need to install more and drivers.
2) there was a failure in the operation of devices or operating system;
Very often, this speaks about the ambulance of the device, but it happens that the OS Operation is blocked and you just need to rain the driver again.
3) New devices or components connected to the computer. There is no in the system suitable Driver And she cannot recognize the connected device.

If Windows Device Manager writes "Unknown Device", it is worth starting with what to find out what it is. Here the device code and the code of the manufacturer will be helped, which are sewn in each component or peripheral device. How to find them? Easily! Click on an unknown device with right-click and select the menu item "Properties":

The properties window will open in which you need to open the "Details" tab and find in the properties list item "Error ID" for Windows 7 and Windows 8 or "Device Instance" code in the case of Windows XP:

In strokes We are looking for VEN identifiers (Vendor - Manufacturer) and Dev (Device Device). In the example, I intentionally chose the defined device so that you can clearly see how it will be further determined.

Now we need to use one of the online database components on the Internet. From myself I can advise two such services. First - Devinfo.

In the search string, we enter the found identifiers and click the "Search" button. In the search results, the desired device is displayed.

If nothing is found - try using the PCIDATABASE service.

Its feature is that the unknown device is not paired, but for each identifier separately.

So, we defined it for an unknown device in Windows Manager. Now we need to figure out what to do with it.

The most correct way out of this situation is download from the manufacturer and install the most last version Drivers. If the device is properly, then in 90% of cases this action will help.

The second option is to check the system for viruses. Sometimes the users have to catch such a malicious readiness that amazes system files And even device drivers.

Does not help? Try to roll back the system to the last workable.

If the problem arose with a USB device connected via the cable - first try simply re-connect it to the next USB port. Is the device unidentified? We must try to replace the cable itself, maybe it is faulty.

When nothing helps ...

With such a situation, most often this "unidentified device" is simply faulty. But before carrying it to the service - try connecting to another computer to check.
