Advanced PC users have long learned how to solve problems such as “One of the connected USB devices is not working properly” on their own. They know their computer to the smallest detail, so questions about how to fix a particular error do not arise. But inexperienced users in this matter are many times more difficult. Some advice from the Internet does not help some, because there is too little knowledge and experience.
Problem
But it doesn’t matter. Any basic PC error can be fixed quickly. To do this, you need to carefully study the instructions and perform step-by-step advice from specialists.
Today's problem is when one of the connected USB devices is not working properly. Most often you will notice this text in the lower right corner of the desktop. Sometimes a special window appears with a notification about this problem.
Background
Most often, an error occurs when connecting any device via USB. This is an ordinary flash drive, and a phone, and a printer, etc. The problem arises both on the early version of Windows 7, and on the late one - "Ten." In this case, your USB may be version 2.0 or 2.0. In general, the essence of the issue does not change from this.
Causes
The error accompanied by the USB connection can be caused by a number of reasons. There really are a lot of them. And they are not always typical. It happens that the fault lies directly and completely with the user who miraculously deleted the drivers or confused the system. There are flaws from the manufacturers of these devices. Poor-quality Chinese flash drives are especially prone to this problem.
Trust but verify
So, you saw a similar error on your screen. In order to avoid unnecessary nerves and waste of a lot of time, it is better to immediately check the device that you are connecting to the port. As mentioned earlier, not all manufacturers are so conscientious. Many create a product just to sell. Hence, system errors occur.
If you bought a new mouse, keyboard or flash drive, immediately check it is working properly before sinning on the USB interface. There are two ways to do this:
- If you have a second PC or laptop, just connect a new device to it. If everything works fine on another system, then most likely the problem is with the computer.
- Take a working device (old mouse, second flash drive, etc.) and insert it into the same port. If the same notification appears, then the matter is really in the connector.
There are a couple of unspoken ways. They do not always give a clear picture of what is happening, but just in case, you can try them out. So, we take the device that gives the error, disconnect it from the PC and turn off the system along with the plug in the outlet. Now you need to hold down the start button on the computer so that the remaining electrical charges leave the motherboard.
Now turn on the PC and connect the USB device when the system is fully loaded. The option is not the best, but sometimes after it really starts to work.
And for those who finally want to make sure that the port is malfunctioning, you can simply disconnect all USB that is on the interface panel. It happens that port congestion can produce a similar error. If you disconnect the equipment that is not needed at the moment, insert the USB flash drive into the rear panel.
Software Methods
Sometimes the problem “One of the connected USB devices is not working properly” cannot be fixed by castling alone. Have to delve into the system. If all the previous methods did not give you a result, try to update the "firewood".
To do this, we are looking for a “Device Manager”. We do it through the command line: hold Win + R on the keyboard and enter devmgmt.msc in the field. You can go to "My Computer", right-click on any place in the window and select "Properties". A window with PC settings will open in front of us, and in the left column you will find the desired section.
So, in the “Device Manager” we select the line “USB controllers”, all USB equipment connected to the system are shown here. Here will be the line “Other devices”, it is in it that our unknown device will be located. We click on his name and try "Update Drivers". We wait until the system itself downloads the necessary files via the Internet, and, possibly, the flash drive will "come to its senses" and work.
Exclamation point
It may be that near this “Unknown device” there is a yellow exclamation mark. In this case, we try to roll back the drivers. We click on it and go to the "Properties". Here you need to find the tab with "firewood" and the button "Roll back". Perhaps it will not be available to you, highlighted in gray. Then select "Delete."
Now you need to return to the "Device Manager" window and select the "Action" section from the top, and update the hardware configuration in it. These steps can fix your problem.
An exclamation mark may appear for another reason. To do this, go to the properties of the equipment that acquired names such as Generic USB Hub, USB Root Controller and USB Root Hub. In the window that appears, select "Power Management" and uncheck the first line. So you prevent the equipment from shutting down to save electricity.
Common Errors and Solutions
As mentioned earlier, the error "One of the connected USB devices does not work correctly" is individual and depends on many factors. Above we examined the most common causes. Now let's briefly describe what kind of malfunctions other users have encountered.
Often this error occurs when the printer is connected. Usually caused by incorrect installation of "firewood". Therefore, you can simply remove them and carefully reinstall them again.
Many problems arise due to mechanical damage. Suppose a cable with a micro-USB connector on one side, and with a USB cable on the other, can be broken or transferred in the middle. It also significantly affects the performance and synchronization of it with a PC.
Another interesting problem that is now becoming less and less common may be incompatibility. Some devices do not support standard 2.0 or newer 3.0. Then it happens that when connecting via USB phone or any other device, you will again see this message. In general, if such a problem arose, it is better to think about changing the motherboard, since the interface standard will continue to change, and there will be even more problems.
Laptop problems
In this case, we encounter problems connecting USB 3.0. Due to the imperfection of this revision of the interface, users have to get out in many ways. A solution was found. In the laptop, it was necessary to adjust the power plan.
To do this, you could go into the standard settings of this parameter or in proprietary software, which is provided by some laptop manufacturers. In Windows, we select the power plan that is currently in use, then go to additional parameters. And already according to a familiar scheme, we prohibit disabling ports to save energy.
findings
If suddenly you can’t connect your phone, external hard drive, USB flash drive and other devices via USB, you don’t need to be upset right away. Firstly, breaking one port out of ten in the system is a common thing. Trying just to use a different connector is easy. Secondly, even if you didn’t succeed in the program plan, you can try reinstalling Windows.
Of course, reinstalling the OS is not a panacea for all problems and the process is quite difficult, especially for those who have never encountered it. Nevertheless, even he can help you.
Perhaps your micro-USB connector does not work due to a real controller failure. It cannot be replaced on the motherboard. This is either to buy a new motherboard, or, as an option, to purchase an external controller with a PCI interface.
