"Seven" in most cases independently copes with the installation of the appropriate software for the equipment, but there are always exceptions. Often, even experienced users have problems with the incorrect operation of computer components and connected devices.

Then the PC owner has to manually correct the situation, for example, search for and install drivers. One of the most frequently asked questions is: “What to do if in Windows Manager 7 discovered unknown device?”, - then we will consider step by step all the options for solving such a problem.

How to identify problem hardware?

In the case when difficulties arose immediately after some changes made by the user himself to the system, for example, new devices or PC hardware components were connected, then finding out the model will not be difficult.

Already simply by the method of phasing out the recently connected peripherals from the PC, you can very soon find out the specific culprit and download the appropriate drivers for it from the manufacturer's official resource.

However, what if this simplest way didn't work? Then you have to use the "Device Manager" in Windows 7.

Utility Launch Methods

To open this service, you need to follow these steps:

1. In the "Control Panel" window, go to the "Hardware and Sound" tab;
2. Further in the "Devices and Printers" subsection, the desired service is located (it is recommended to run it with extended permissions).

Second method:

1. summon context menu from "My Computer";
2. Then click "Management";
3. Next, in the "Utilities" section, find the desired dispatcher and open it.

Additional way:

Note: searching for a problematic device will not require any effort and time from the user, since the section with undefined equipment will already be expanded, and the component itself, as a rule, is always marked with a special yellow icon.

Troubleshooting Techniques

First you need to use the most elementary methods.

Automatic driver search

First of all, you need to make sure that automatic mode detection and installation of appropriate software for computer devices.

To this end, you only need to take a few steps:

1. Enter the "Control Panel";
2. Next, open the "Hardware and Sound" tab;
3. Then go to "View devices and printers";
4. After that, in the "Device Installation Options" section, make sure that the item is activated: "Yes, do this automatically." If there is no activation mark in this column, then be sure to put it;
5. Open "Properties";
6. Click "Update driver";
7. Ready.

With absence positive result proceed to the following instructions:

1. Restart PC;
2. Call the context menu from a blank field in the dispatcher window and click "Update configuration";
3. Install possible Windows updates 7;
4. Carry out a complete analysis of the system by antivirus for the presence of malicious utilities in it;
5. Seize Opportunities third party applications to update and install drivers such as Driver Booster.

Very often, such a useful built-in tool in Windows 7, the “New Device Setup Wizard”, helps in this situation. To use it, you need to take only a few steps:

1. Launch the "Control Panel";
2. Then go to "Hardware and Sound";
3. Then click "Add devices";
4. Wait for the search process to complete.

Sometimes all these actions are ineffective. Then you should proceed to the manual search and installation of the necessary software. The instructions below will make it easy and fast.

Solve the problem manually

If you know the model of the device, then finding drivers for it is very simple. To do this, just visit official resource manufacturer and install the appropriate software from there. But if the model is unknown, then first you should find out the identifier of the problematic equipment, which is indicated in its properties, opened through the device manager.

You can simply enter the numbers next to VEN and DEV in the search bar of the browser, after which the global network will show the name of this equipment.

The algorithm consists of the following steps:

1. In the Windows 7 manager, right-click on the problematic hardware;
2. Then click "Properties";
3. Next, go to the "Details" tab;
4. In the "Property" list, click on "ID" or "Instance Code";
5. The combination of characters you are looking for will be displayed.

Due to the constant increase in the level of computer literacy, it is no longer a secret for most PC users that the operating Windows system does not know how to work directly with the hardware components of the computer. For Windows to interact with hardware, a special software, which will serve as a link between the OS and PC components. Such software is called drivers. The main task of the driver is to convert standard operating system commands into a set of commands understandable specific device that interacts with the system. As a rule, drivers for basic computer devices, such as CPU or HDD, shipped with the operating system. However, in order to work with other devices, such as a video card, you need to install the appropriate driver.

But what if you connected a system or peripheral device to your computer for which you do not have drivers? It even happens that the model name is not indicated anywhere on the device itself, and Windows defines the connected device as “unidentified”. In this case, you can use one old, proven way to search for drivers. To do this, we, first of all, will need to find out the personal identifier of the equipment.

Finding the Hardware ID

To find out the equipment ID, you need to go to the Manager Windows devices. You can access Device Manager by going to Start>Control Panel>Hardware and Sound>Devices and Printers. You can also open the Device Manager much more simply and fast way. Press keyboard shortcut Win+R and type in the line Run the following command: devmgmt.msc.

Look for an unrecognized device marked in Device Manager with a yellow symbol with exclamation point. Click on it right click mouse and select from the context menu Properties. In the properties window, go to the tab Intelligence.

Then expand the dropdown below the item Property and select an item from the list Hardware ID.

If it suddenly happens that there is no item in the list of properties Hardware ID, then you can search for the identifier in points Compatible IDs, related, Parent or Path to Device Instance.

Once you have found the hardware ID, you need to copy it to your clipboard.

Search for a driver on the Internet by ID

There are two ways to search for drivers on the Internet by hardware ID. The first is to simply paste the copied ID code into the search bar of the Google or Yandex site and thus search through all sites with drivers. Basically this method works, however, when looking for drivers for an uncommon device search system will give you a huge bunch of links, most of which will be links to driver search forums, links to English-language sites, as well as broken links. As a result, searching for a driver will take you a lot of time and effort, and there is still no guarantee that the driver found will exactly fit your device.

The second method involves searching for a driver by identifier on specialized sites. Using this method, although you limit the field for searching for a driver to one or several sites, you have a much better chance of finding exactly the driver you need.

One of the most popular sites for finding drivers by ID is the site DevID, located at this address: devid.info/ru.

This resource contains a huge database of drivers for all system and peripherals, including drivers for biometric devices, drivers for joysticks, and even drivers for modern tape drives.

Having entered the DevID website, paste the previously copied hardware ID code into the search bar and click on the button Search. However, searching by the full ID code is rarely successful. Most often, instead of search results, you will see the inscription: We can't find the driver *your driver ID*.

In this case, you can try to shorten the name of the identifier a little, for example, by removing all characters after the sign & .

As you can see, now the site's search engine is already producing some results. Of course, searching by the short code of the hardware identifier somewhat reduces the likelihood of an exact match of the found drivers to your hardware model, but this result is still better than nothing. In addition, if you browse the search results page a little, you will most likely find the driver you need, since it will be much more common than the rest.

Thus, you can install any devices in the system, even if you do not know their name, and you do not have a driver disk for them. And after you find and install the driver for an unknown device, it would be good to make a backup this driver so that in the future you no longer bother with searching for drivers by ID. To learn more about how you can back up drivers, see this article: Saving backups drivers.

A detailed description of how you can quickly determine the identifier (ID) of the device for further selection and installation of the necessary drivers.

A small introduction

The problem of finding drivers for the most different devices already repeatedly raised in various materials on this resource. Most complete guide on this topic is: .

Within the framework of this article, only the process of determining the device ID for subsequent search and installation of the necessary drivers will be considered. Unlike the method proposed above, we do not have to download and install additional utilities, we will limit ourselves to the built-in Windows tools. This material is primarily aimed at beginners.

General information about the device ID

For many novice users, the phrase "device ID" will not say anything at all. Before moving on to the main part of the article, it makes sense to understand what it is and why a certain identifier is needed.

It so happened that computer technology comprises huge amount a variety of chips, devices and other details. For all this to somehow work with Windows, you need to install a small layer - drivers. They are also very different and work only with certain devices. Roughly speaking, if Wi-Fi does not work for you, then before installing all the drivers in a row, you need to find out which wireless module you have and what driver is needed for it. And this is where the problems begin. How to find out which module is worth?

It is for this purpose that the device identifier was invented. It contains information about the manufacturer and model of the equipment, which will allow you to avoid a huge pile of problems and install the exact driver you need.

Technically, this identifier is a set of strings that are stored directly in the device or chip itself. Depending on the type of equipment and connection method, they look like VENxxxx&DEVxxxx, VIDxxxx&PIDxxxx, ACPI... etc. Instead of xxxx usually there are 4 digits in hexadecimal (0 - 9 and A - F). The first four numbers indicate the manufacturer, the second about the device model. Sometimes other lines like SUBSYS that talk about modification. It is on these lines that forum participants in the section of our forum find the necessary drivers.

And so, we have more or less figured out the question of what the equipment identifier is and why it is needed. Let's go straight to its definition.

Determining the device ID

AT operating systems Windows families this process is pretty much the same. First you need to open, select desired device and find this very identifier in its properties. Let's consider this in more detail using the example of different systems.

Windows 7

First of all, we need to go to Properties of the system. This is done either through Control Panel - System, or by pressing the keys win + break, or through the properties of the Computer in the Start menu:

After that, click on the Device Manager in the upper left:

In the list of devices, find the one you need and go to its properties:

Usually devices without drivers or with incorrect installed drivers marked with yellow icons. They are of primary interest to us.

After that, in the window that appears, go to the tab Intelligence and select in the box:

The lines we need should appear in the window below. You don't need to copy all of them, just one with VEN/VID, DEV/PID and SUBSYS/REV codes is enough. For USB devices like webcams or Bluetooth adapters, these lines are different:

And for touchpads and some system devices, the value of the hardware ID field can be like this:

On systems with Windows 8, 8.1 and 10, the procedure for determining these lines is generally similar. Let's consider it.

Windows 8, 8.1 and 10

For start Device Manager In addition to the methods mentioned above, you can also use the built-in search system:

After that, select the desired device:

And go to its properties through the context menu. After that go to the tab Intelligence and choose in the box:

As you can see, there is nothing complicated. To complete the picture, let's look at how this is done on Windows XP.

Windows XP

First, go to My Computer Properties:

After that, on the tab Equipment press the button:

After that, select the desired device from the list and open its properties.

Today, USB is one of the most common protocols for transferring data between a computer and a connected device. Therefore, it is very unpleasant when the system does not see the devices connected to the corresponding connector. Especially a lot of problems arise if on a PC via USB there is an interaction with a keyboard or mouse. Let's see what factors caused this problem, and determine the methods for its elimination.

In this article, we will not analyze the problems with the visibility of the device associated with its inoperability, because in this case, this equipment should be replaced or repaired. The article will deal with cases where the problem is caused by malfunctions or incorrect settings of the system or PC hardware. In fact, there can be many reasons for such a malfunction, and for each of them there is its own solution algorithm. We will talk about specific ways to fix this problem below.

Method 1: Microsoft utility

In many cases, a utility from Microsoft, specially created for this purpose, can solve the problem with the visibility of USB devices.

Method 2: "Device Manager"

Sometimes a USB hardware visibility problem can be solved by simply updating the configuration in "Device Manager".

1. click "Start". Click "Control Panel".



2. Come in "System and safety".



3. Now open "Device Manager" by clicking on the corresponding inscription in the block "System".



4. The interface will start "Device Manager". The problematic device in the list can either be displayed in the block "Other devices", or absent altogether. In the first case, click on the name of the block.



5. A list of devices will open. Problematic equipment can be indicated there both under its real name, and appear as "USB mass storage device". Right-click on its name ( PKM) and select "Update Configuration...".



6. Device search will be activated.



7. After it is completed and the configuration is updated, it is quite possible that the system will begin to interact normally with the problem device.

If the desired equipment is not displayed at all in "Device Manager", click on the menu item "Action" and then select "Update Configuration...". After that, a procedure similar to the one described above will occur.

Method 3: Update or reinstall drivers

If the computer does not see only a specific USB device, then there is a chance that the problem is related to incorrect installation drivers. In this case, they need to be reinstalled or updated.

If a this option did not help, then there is another method.

1. Click in "Device Manager" by device name PKM. Select "Properties".



2. Go to tab "Driver".



3. Click on the button "Rollback". If it is not active, click "Delete".



4. Next, you should testify your intentions by clicking the button OK in the dialog box that appears.



5. The procedure for uninstalling the selected driver will be performed. Next click on horizontal menu windows by position "Action". Select from the list "Update Configuration...".



6. Now the name of the device should again be displayed in the window "Device Manager". You can check if it works.

If the system could not find the appropriate drivers or the problem was not solved after installing them, then you can use the services of specialized programs to search and install drivers. They are good because they will find matches on the Internet for all devices connected to the PC and perform automatic installation.

Method 4: Set up USB controllers

Another option that can help in solving the problem under study is to configure USB controllers. It is carried out in the same place, that is, in "Device Manager".

If this does not help, then you can reinstall the drivers for the above group elements "USB Controllers" using the same methods as described in the presentation Method 3.

Method 5: Troubleshooting the port

It is possible that your computer does not see a USB device simply because its corresponding port is faulty. In order to find out if this is the case, if there are several USB ports on a stationary PC or laptop, try connecting the equipment through a different connector. If this time the connection is successful, then this means that the problem is in the port.

To fix this problem, you need to open the system unit and see if it is connected given port to the motherboard. If it is not connected, then connect. If there was mechanical damage or other damage to the connector, then in this case it is necessary to replace it with a serviceable version.

Method 6: Static Relief

In addition, you can try to remove static electricity from motherboard and other PC components, which can also cause the problem we are describing.

There is also a possibility that the computer does not see the hardware because there are already many USB devices connected to it. The system just can't handle the load. In this case, we recommend that you turn off all other devices, and connect the problematic equipment to the back system block with the appropriate connector. Perhaps this recommendation will help solve the problem.

Method 7: "Disk Management"

The problem with the visibility of the connected USB device, in this case only a flash drive or external hard disk, can be solved using the system's built-in tool "Disk Management".

1. Click Win+R. Enter in the field of the appeared shell:

   Apply by pressing OK.



2. Tool interface starts "Disk Management". It is necessary to trace whether the name of the flash drive is displayed and disappears in the window when it is connected to the computer and disconnected. If nothing new visually happens at the same time, then this method will not work for you and you need to solve the problem by other methods. If changes occur in the list of connected drives when a new media is attached, then you can try to solve the problem with visibility using this tool as well. If there is an inscription opposite the name of the disk device "Unallocated" then click on it PKM. Next choose "Create a simple volume...".



3. will start "Basic Volume Wizard...". Click "Further".



4. Then a window will open where you need to specify the size of the volume. Since in our case it is necessary that the size of the volume be equal to the size of the entire disk, then click here "Further" without making changes.



5. The next window requires you to assign a drive letter. In the corresponding field, select a character that is different from those letters that are already assigned to other drives in the system. Click "Further".



6. The following settings window opens. Here in the field "Volume Label" you can enter a name that will be assigned to the current volume. Although, this is not necessary, as you can leave the default name. Click "Further".



7. The next window will provide a summary of all the data entered in the previous steps. To complete the procedure, just click on the button "Ready".



8. After that, the volume name and status will appear opposite the media name. "Fixed". Next click on it. PKM and select "Make Section Active".



9. Now the computer should see the flash drive or external hard drive. If this does not happen, then restart the PC.

There are situations when, when opening a tool "Disk Management", the volume that belongs to the flash drive already has the status "Healthy". In this case, you do not need to create a new volume, but you need to perform only those manipulations that are described starting from point 8.

If, when opening the tool "Disk Management" you see that the drive is not initialized and has a single volume that is not allocated, which means that most likely this drive is physically damaged.

Method 8: Power settings

You can solve the problem with the visibility of USB devices by making some manipulations in the power settings. Especially often this method helps when using laptops that interact with the connected equipment via the USB 3.0 protocol.

1. Go to "Control Panel", and then to the section "System and safety". How to do this, we discussed in the analysis Method 2. Go to position here "Power".



2. In the window that opens, find the current power plan. There should be an active radio button next to its name. Click on position "Setting up a power plan" near the named position.



3. In the shell that appears, click "Change advanced options...".



4. In the window that appears, click "USB settings".



5. Click on the inscription "Pause option...".



6. The specified option will open. If there is a value "Allowed", then you should change it. To do this, click on the indicated inscription.



7. From the drop-down list, select "Forbidden", and then click "Apply" and OK.

Now you can check if they will work USB devices on this PC, or you need to move on to other ways to solve the problem.

Method 9: Eliminate the virus

You should not exclude the possibility that the problem with the visibility of USB devices arose as a result viral infection computer. The fact is that some viruses specifically block USB ports so that they cannot be detected using an anti-virus utility connected from a USB flash drive. But what to do in this situation, because if the regular antivirus missed malicious code, then it is now of little use, but you can’t connect an external scanner for the above reason?

In this case, you can make hard check disk with an antivirus utility from another computer, or use a LiveCD. There are quite a few programs designed for these purposes, and each of them has its own nuances of operation and management. But it makes no sense to dwell on each of them in detail, since for the most part they have an intuitive clear interface. The main thing when detecting a virus is to be guided by the tips that the utility displays. In addition, on our website there is a separate article devoted to such programs.

There are quite a few ways to restore the visibility of USB devices in Windows 7, but this does not mean that all of them will be effective in your particular case. Often you have to try many options before finding a suitable way to solve a problem.

Hardware ID (HID) is a unique identifier generated from serial number motherboard and other computer hardware. All permanent licenses are tied toHID.

There are two ways to determine the HID of your computer.

Attention! No matter how you get the HID, it will always be the same for one computer and for generator appHID and for radioserver configurator. Starting with SmartPTT 9.2, HID depends on the Windows OS language. Please generate the HID using the language in the OS settings which will be used at work.

1. Configurator radioserver

Open Radioserver configuratorSmartPTT and go to Settings -> Additional modules -> Licenses . On this tab, you can view the available licenses for the software, and collect the hardware ID.

In the area of Activation , click on the button Get and the hardware ID will appear in the box above the button.

To copy the HID to the clipboard, click on the button Copy . Once the HID has been copied, paste the HID into any text file or the text of an email to send it to the person who requested it from you.

In cases where SmartPTT Radioserver is not yet installed on your computer, you can use the application SmartPTT Hardware ID which is an independent HID generation software.

Download this app for SmartPTT 9.1.2 and below you can follow the link HID Generator for versions 9.1.2 and below

Download this app for SmartPTT 9.3.28 and above you can follow the link HID Generator for versions 9,3,28 and higher

Please note that the HID that is assembled latest version generator can be used for SmartPTT 9.3.28 and higher.

HID generation for SmartPTT from version 9.2 to version 9.3.28 can be done only through the Radioserver Configurator.

Unzip this archive and run the executable HIDSA . exe .

Identifier– the identifier of your equipment, which must be transferred to SmartPTT technical support and which will be used to generate a license for SmartPTT software.
