The device is not recognized - what to do? Installation of computer equipment

The device is not recognized? What to do in this case? Technique often breaks at the most inopportune moment. How quickly to restore it, and will be considered in the framework of this article.

general information

The greatest number of problems occur when trying to connect USB. When an external hard drive, a USB flash drive, a printer, or something else is connected to the computer, he often writes that the device is not recognized. What can I do to fix this problem? Most of all in this plan sin USB 2.0 and 3.0. It should be noted that there can be a great number of reasons for this phenomenon, so there is no definite universal solution. Therefore, within the framework of the article, several options will be presented, what to do. One will work there, the other - otherwise, to solve the problem, it is necessary, perhaps, to try them all. And even this does not guarantee the probability that the identification will succeed. Alas, much is above the power of the ordinary citizen and his home workshop. So, the device is not recognized. What to do?

First aid

Initially, make sure that the presence of an error that indicates that the computer does not recognize the device is not a consequence of its malfunction. In other words, if a flash drive is often dropped, then it could easily fail. In this case, you can connect it to another computer. If it does not work there, then the problem is in the device itself. In this case, you will have to diagnose not a computer, but removable media, a printer or another supplement. If the second computer does not exist, but it is known that the device previously worked quite successfully, then you can perform the following actions:

1. You must turn off the device and turn off the computer. Now we are most interested in computer equipment. Remove the mains plug from the power outlet. Then you need to press and hold the power button for five seconds. This is done in order to remove the remaining charge from the motherboard and accessories.
2. Then you should turn on the computer and connect the device that was not working to it after the operating system is loaded. After such manipulations, there is a possibility that the device will work.

As a quick alternative, you can try changing ports if the USB device is not recognized. What if it did not help, we'll discuss.

Working with Device Manager

This is a slightly more complicated option. Initially, you should run the device manager itself. You can do this through the menu or via quick launch. The last option can be used by pressing Win + R. In the window that opens, there will be a line in which to enter devmgmt.msc and press the enter key. Where can we find our unidentified device? Most likely, it can be found in the sections :

1. USB controllers.
2. Other devices.

How can you find it among other computer equipment? This option is suitable if the device is located in the "Other devices" section. It will be signed as an "unknown device". When it is found (and if there is an Internet connection), by clicking on it with the right mouse button, you can see the drop-down menu. In it you need to select an item like "Update driver", and the operating system will fix the device. However, it is not recommended to place great hopes on this. Such pessimistic words should be added because of the program-human factor, because of which the drivers in the specified location on the Net simply will not turn out.

Working with Controllers

If the identification went the other way, then it's a little more complicated. So, initially you will need to right-click on the device. From the list, select Properties. In the window that opens, go to the "Driver" tab. If available, then click on the "Rollback" button. In the opposite case, "Delete". After that, you will need to go to the device manager and select "Update hardware configuration" via "Action". After that, you can see if everything will work as it should.

Here all the recommendations are fulfilled, and the USB device is not recognized. What to do in this case? Then you should try to install the driver manually. Before it is very desirable to remove. You need to search the necessary program on the Internet and install it yourself. And if one does not fit, then do not give up. You need to try another driver. If, for example, software shells for printers are installed, then you should try not only for a particular device, but also for universal configurations. But here are the recommendations, and the device is not recognized. What to do in this case?

Power supply

This is a rather unexpected, but at the same time effective method. There are two variants of changes. Consider the first. Initially, through the control panel, we need to open a window that is responsible for the power supply. After that, select the circuit that is used, and click on the button "Change additional power settings". Then you need to prohibit disconnecting devices or USB ports in order to save power. After such manipulations, the computer equipment should work without problems. If Windows does not recognize the device even after such manipulations, then it's hard to advise what to do. At home, most likely, it will not be possible to restore his work.

Conclusion

And now everything is done, but the device does not work. Okay, if it's a printer or a scanner. And what if you did not manage to reanimate the flash drive or external hard drive, which contains extremely important information? Are there any options for this case? Yes, it is possible to restore data, but it is necessary to understand the level of professional knowledge necessary for this. Well, we should not forget about the fact that we need a very modern equipment, which can only be found by specialists who are engaged in the restoration of devices. Therefore, considering all the home options, it should be noted that there remains only an appeal to those who earn this by bread.
