The device is not recognized? What to do in this case? Technology often breaks at the most inopportune moment. How to quickly restore it, and will be considered in the framework of this article.
general information
Most problems arise when trying to connect USB. When an external hard drive, flash drive, printer, or something else is connected to a computer, it often writes that the device is not recognized. What to do to fix this problem? Most of all in this regard, USB 2.0 and 3.0 sin. It should be noted that there can be a great many reasons for such a phenomenon, therefore, one cannot talk about the existence of a definite universal solution. Therefore, the article will present several options for what to do. One will work there, the other - otherwise, in order to solve the problem, it may be necessary to try all of them. And even this does not guarantee the likelihood that the identification will succeed. Alas, a lot is above the power of the average man in the street and his capabilities at home. So, the device is not recognized. What to do?
First aid
Initially, you should make sure that the presence of an error that indicates that the computer does not recognize the device is not a result of its malfunction. In other words, if the flash drive was often dropped, then it could easily have failed. In this case, you can connect it to another computer. If it fails there, then the problem is in the device itself. In this case, you will have to diagnose not a computer, but a removable media, printer, or other addition. If there is no second computer, but it is known that the device previously worked quite successfully, then you can perform the following actions:
- You should turn off the device and turn off the computer itself. Now we are most interested in computer equipment. Unplug the power cord from the 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 components.
- Then you should turn on the computer and connect the previously inactive device 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 to do if this does not help, we will now discuss.
Work with the device manager
This is a slightly more complicated option. Initially, you should start the device manager itself. This can be done through the menu or through a quick launch. The last option can be used by pressing Win + R. In the window that opens, there will be a line in which you should enter devmgmt.msc and press the enter key. Where to look for our unidentified device? Most likely, it can be found in the sections :
- USB controllers.
- Other devices.
How to recognize him 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), then by right-clicking on it, you can see the drop-down menu. In it, you need to select such an item as “Update driver”, and the operating system will fix the device. True, to pin high hopes on this is still not recommended. Such pessimistic words should be added because of the human-software factor, because of which drivers simply will not appear in the place indicated on the Web.
Work with controllers
If the identification went the other way, then here is a little more complicated. So, initially you will need to click on the device with the right mouse button. From the list you need to select "Properties". In the window that opens, go to the "Driver" tab. If available, then click on the "Roll back" button. Otherwise, “Delete.” After that, you will need to go to the device manager and select “Update hardware configuration” through “Action”. After that, you can see if everything will work as it should.
Here are all the recommendations implemented, but the USB device is not recognized. What to do in this case? Then you should try to install the driver manually. Before that, it is very desirable to remove it. You need to search for the necessary program on the Internet and install it yourself. Moreover, if one did not fit, then you should 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 specific device, but also universal configurations. But here the recommendations are implemented, but the device is not recognized. What to do in this case?
Power supply
This is a rather unexpected but effective method. There are two options for change. Consider the first one. Initially, we need to open the window through the control panel, which is responsible for the power supply. After that, select the scheme that is used and click on the button “Change advanced power settings”. Then you need to prohibit disconnecting devices or USB ports in order to save energy. After such manipulations, computer equipment should work without problems. If Windows does not recognize the device even after such manipulations, then it is already difficult 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 scanner. But what if you are unable to reanimate a USB flash drive or external hard drive that contains extremely important information? Are there any options for this case? Yes, it is quite possible to recover data, but it is necessary to understand the level of professional knowledge necessary for this. Well, we should not forget that we need very modern equipment, which can only be found by specialists who are engaged in the restoration of devices. Therefore, given all the home options, it should be noted that there remains only an appeal to those who earn a living from this.
