As usual, One of the most useful elements in any type of computer are USB ports (Universal Serial Bus)which allow you to connect multiple external devices to the computer, be it a headset, a printer, a USB flash drive or even a mobile phone to import or export information of interest. Thus, the simplicity and functionality of USB is completely remarkablegiven that it has been specially designed to be able to connect or disconnect at will, other equipment that is used to carry out various actions, on both Windows and Mac.
Nevertheless, many times these ports do not work correctly and with this, endless doubts begin to be generated about its causes and the most effective solutions to repair it. But before learning about such tactics, it is essential that you make sure that it is the port that is presenting defects and it is not about damage produced in the other device that is connecting to the computer. To provide you with timely clues, we recommend link the external device to another USB port and in case it is detected normally, you can conclude that the previous one is presenting faults.
Now, once you make sure that you must repair the USB port, you must begin to inquire about the number of problems that may exist and in such a way, find the reason that specifically is causing problems in your equipment. Later, you can look for the most ideal solution to fix USB port that has stopped working. Indeed, below we present two sections through which you will achieve identify the cause of the problem and in another, know some simple steps and tricks to perform to solve said damage.
What are the causes for which a USB port can stop working?
Although it is true, they can there are countless reasons why a port of this type stops working on your computer. But, generally, users tend to conclude that they have a common problem and thus, these are constantly repeated in various cases.
Therefore, we will present you below the most common reasons for a USB port failing:
Quickly remove or insert a USB device
Although you probably think that quickly inserting or disconnecting a USB device to the indicated port, only deals damage to the linked artifact; that is not true at all. It is necessary to note that when carrying out these types of actions, the unit may lose the stored data or be corrupted in such a way that no formatting may be able to reconfigure it. That is, if it can powerfully affect the other teams.
However, when you repeatedly and quickly plug and unplug this storage hardware, the port stops responding to other hardwarebecause a timing problem is generated whereby the computer is prevented from detecting any external equipment. Consequently, being in this state, this port will not be able to recognize any device and will not work correctly.
5v and Gr cables badly connected
This is considered one of the most serious errors that these peripherals can suffer, since It is practically irreparable damage.. Because, by not connecting the 5v t Gr cables well, 5 volts to spare is supplied to the circuit rather they should be used for sending and receiving data.
Consequently, it is caused permanent breakage of various computer components and in addition, it generates burns in the USB port that are uncorrectable and also in the USB circuits of the motherboard.
Sometimes, a computer can be working without any problem when faults of this type arise. But, noticing that the USB port is not working properly, is an accurate indication that the motherboard is also involved in the damage. Thus, it is very important that these cables are connected in the corresponding place.
Bad or dirty ports
Another of the most common causes why a USB port does not work in the most indicated way, It is due to the dirt accumulated in them and their poor condition. And it is that its physical form allows it to accumulate considerable traces of dust and even more so when its users do not worry about cleaning from time to time with a brush, towel or a handheld vacuum cleaner.
Also, these ports tend to get dirty because of the Pendrives that fit into themsince most of this equipment is kept in bags, pockets or purses that usually, accumulate impurities.
Driver issues
In various circumstances, problems related to hardware damage are due to faults with respect to the computer’s drivers. Taking into account that each piece of hardware needs to have a special driver to work correctly and also, this must be the appropriate one. But, many people do not know how to detect if their computer exhibits a problem of this kind.
In this sense, we indicate the process to find out if there are problems with the drivers, which is extremely easy. you just have to enter device manager and in case you see there a yellow signit is indicating that the controllers have problems or are outdated (the most usual).
Therefore, it is required to keep them updated and for this to solve it, you must choose the port and click on the “Update” button. Now, in case this is generated due to incompatibility, you can use software for it, such as “Driver Booster”.
Having viruses on the PC
It is no secret to anyone that viruses present in a computer can cause extremely notable damage and the non-functioning of a USB port can also be caused by these malwareswhether they are present on the same PC or even on the device that is connected through said port.
Indeed, if you know that your computer has not been working correctly for the last few days, since perhaps has the presence of a virus and in the same way, the good work has been cut short, do not doubt that it is because of it. So keep in mind the importance of always having powerful antivirus.
Failure due to power damage
If you don’t know, most of the external devices that connect to the computer’s USB port they need food from it. Therefore, if you decide to link one of them to the computer and it does not perform any action, there is probably a power failure.
To know some signs that the power supply of the computer is damaged, we inform you that commonly computers often reboot or crash without explanationthey exhibit great noise and a kind of smoke smell, have problems starting, among others.
It does not recognize the USB: Error code 43
This error refers to a specifically hardware problem on the device that is connected via the cable, i.e. the external device and indeed, indicates bad connection or damaged cable. Which in short means that it is a device whose hardware cannot be correctly identified on the PC.
Many times, to avoid the code 43 error, it is recommended to disable energy saving Y “universal bus controller” in the device manager of the computer.
Steps and tricks to fix USB ports that have stopped working
Once the most common reasons for which a USB port does not allow you to satisfactorily connect external devices are known, It is necessary to detail the most effective processes and tricks to be able to repair these ports and after that, ensure its operation.
These methods are listed below:
Perform a physical exam
Most common physically inspect the status of the input device. Thus, you will be able to see if it has something stuck inside and if so, remove it gently with a kind of brush or a thin plastic.
You can also perform a test by inserting a USB memory and thus, see and analyze if it moves to the sides easily; which you must do with great delicacy to avoid damaging it further. Added to that, if it connects and disconnects immediately, it is most likely that there is a physical problem with it.
In this sense, if you feel a lot of movement when doing the test, you can confirm that the port is broken or bent and the best will be take it to a professional to change it quickly.
Replace USB port
If you carried out a physical study of the east and it did not generate any type of failure (in plain sight), since it does not move or anything like that; you should opt for other solutions. One of them and to which many users resort, is to replace the usb port and well, insert the external device in a different port.
Indeed, if said device is detected by the system and it does not present faults in its operation but rather the process arises normally, what may be happening is that the USB port tested at first is getting damaged.
computer restart
Although it is true, one of the things that people most often do when their computer does not work correctly, is to turn off your computer for a moment or restart it. Which, despite the fact that it seems simple and even ineffective, works in many situations.
Indeed, if you’re having trouble connecting other devices to your computer and importing or exporting information, it’s a good thing you choose to perform a simple reset and so, when the PC is turned on again, the same system should detect the other device. If not, it is necessary to resort to other tricks.
Device Manager in Windows 10
In many cases, the fault is related to a driver and in order to check this, it is necessary go to device manager (if you have a Windows 10 computer). Here is the procedure to follow:
- Located in the start menu, click the right mouse button and choose the option “Device administrator”.
- Generally, this device manager lists all devices that are connected to the computer and groups them by specific categories. There, you must locate “Universal Serial Bus Controllers” and double click on it.
- Subsequently, a small list will expand in which it is necessary that Look for the “USB Host Controller” selection. Usually, it has a longer name on each PC, but it must include these three words.
- In case you don’t get that option, USB port is failing. To solve it, click on the button “Find hardware changes” at the top.
- After that, it will start a verification procedure that should detect it and any connected devices.
- Next, if the port still does not work, you must reinstall drivers and to do so, click on the USB host controller items, for now uninstall each of them.
- Once they are uninstalled, you need to restart the computer and thus, the drivers will be reinstalled automatically. What finally, must solve the…
