In general, some of the most useful elements in any type of computer are the USB (Universal Serial Bus) ports , which allow multiple external devices to be connected to the device, be it a headset, a printer, a USB flash drive or a mobile phone to import or export information of interest . Therefore, the simplicity and functionality of USB is completely remarkable , given that it has been specially designed to be able to connect or disconnect at will, other equipment used to carry out various actions, both on Windows and Mac .
However, many times these ports do not work correctly and with that, they begin to generate endless doubts about their causes and the most effective solutions to repair it . But before knowing these tactics, it is essential that make sure that it is the port that is presenting defects and that it is not about damages produced in the other device that is connecting to the computer. To provide you with appropriate indications, we recommend to link the external device to another USB port and in case it is detected normally, you can conclude that the previous one is presenting failures .
Now, once you make sure that you need to repair the USB port, you need to begin to inquire about the amount of problems that may exist and thereby, find the reason that is specifically causing inconvenience in your device . You can then find the most ideal solution to repair the USB port that has stopped working . In fact, here are two sections through which you will be able to point out the cause of the problem and in another, know some simple steps and tricks to perform to solve said damage >.
What are the reasons why a USB port may stop working? ?
While it is true, there can be countless causes for which such a port stops working on your computer . But, generally, users usually conclude that they have a common problem and thus, these are repeated constantly in various cases .
Therefore, we will present below the most common reasons given when a USB port fails :
Remove or insert a USB device quickly
Although you probably think that quickly inserting or disconnecting a USB device to the indicated port, only causes damage to the linked device ; That is not true at all. It should be noted that when performing this type of action, the unit may lose the stored data or be corrupted in such a way that no formatting can be able to reconfigure it. In other words, if it can strongly affect the other equipment .
However, when you connect and disconnect this storage hardware repeatedly and quickly, the port stops responding to other hardwares , because a timing problem is generated from which prevents the computer from detecting any external equipment . Consequently, being in that state, this port will not be able to recognize any device and will not work correctly .
5v and Gr cables improperly connected
This is considered one of the most serious errors that these peripherals can suffer, since is practically irreparable damage . Because, by not connecting the 5v t Gr cables properly, 5 volts is left over to the circuit that should rather be used for sending and receiving data.
Consequently, causes the permanent breakage of several components of the computer and also causes burns in the USB port that are incorrigible and also in the USB circuits of the motherboard.

Sometimes, a computer may be working without any problem when failures of this type arise. But, noting that the USB port is not working properly, is a precise indication that the motherboard is also involved in the damage . Therefore, it is very important that these cables are connected in the corresponding place .
Ports in poor condition or dirty
Another of the most common reasons why a USB port does not work as indicated, is due to the dirt accumulated in them and its bad condition . And it is that its physical form, allows to capture significant remains of dust and even more so when its users do not worry about cleaning every so often with a brush, towel or a handheld vacuum cleaner.
Also, these ports tend to get dirty because of the Pendrives devices that enter them , since most of these devices are kept in bags, pockets or purses that usually accumulate impurities .
Driver issues
In various circumstances, problems related to hardware damage are caused by failures with respect to computer drivers . Taking into account that, each piece of hardware needs to have a special controller to work correctly and in addition, this must be the appropriate one. But, many people don’t know how to detect if their computer exhibits a problem of this kind .
In this sense, we indicate the process to know if there are problems with the drivers, which is extremely easy. You just need to go to the device manager and if you see there a yellow sign , it’s telling you that the drivers have problems or are outdated (most usual).
Therefore, it is necessary 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 by incompatibility, you can use software for this, such as “ Driver Booster ”.
Have 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 malwares , whether they are present in the same PC or even on the device that connects through that port.
Indeed, if you know that your computer has not been working properly for the last few days, since perhaps has a virus and in the same way, good work has been truncated , do not doubt that it is because of it . So keep in mind the importance of having powerful antivirus always.
Failure of damage to the power
If you don’t know, most external devices that connect to the USB port of the computer need power from it . Therefore, if you decide to link one of them with the equipment and it does not perform any action, it is likely that there is a damage to the feeding .
To know some signs that the computer’s power supply is broken, we inform you that commonly the equipment is usually restarted or blocked without explanation , they exhibit great noise and a kind of smoke smell, they have trouble starting, among others.
Does not recognize USB: Error code 43
This error refers to a specific hardware problem in the device that is connected through the cable, that is, the external device and, in effect, indicates bad connection or damaged cable . In summary, this means that it is a device whose hardware cannot be correctly identified on the PC .
Many times, to avoid error code 43, it is recommended to disable power saving and “ Universal bus controller ” in the device manager of the computer.
Steps and tricks to fix USB ports that have stopped working
Once known the most common reasons why a USB port does not allow to connect external devices successfully, it is necessary to detail the most efficient processes and tricks to be able to repair these ports and after that, ensure its operation.
Then these methods:
Take a physical exam
Most commonly, it is to physically inspect the state of the input device . Thus, you can 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 placing a USB stick and thus see and analyze if it moves easily to the sides ; which you must do with extreme delicacy to avoid damaging it further. In addition to that, if it is connected and disconnected next, it is most likely that there is a physical problem in 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 it is best to take it with a professional to change it quickly .
Replace the USB port
If you carried out a physical study of the east and did not generate any type of failure (in plain sight), since it does not move or anything like that; You must opt for other solutions. One of them and that many users turn to, is to replace the USB port and, well, introduce the external device into a different port.
In fact, if this device is detected by the system and does not show any malfunctions but the process arises normally, what may be happening is that the USB port tested at the beginning is being damaged >.
Computer restart
While it’s true, one of the things people usually do when their computer is not working properly, is shutting down your computer for a moment or restarting it . Which, although it seems simple and even ineffective, works in many situations .
Indeed, if you have problems connecting other devices to the computer and importing or exporting information, it is good that you choose to carry out a simple restart and thus, when the PC is turned on again, the same system should detect the other device . If this is not the case, it is necessary to resort to other tricks.
Device Manager in Windows 10
In many cases, the fault is related to a driver and to check this, it is necessary to go to the device manager (if you have a Windows 10 computer). Here is the procedure to follow:
- Located in the start menu, right-click and choose the option “ Device Manager “.
- Generally, this administrator of devices list all those connected to the computer and group them by specific categories . There, you must locate “ Universal Serial Bus Controllers ” and double click on it.
- Subsequently, a small list will be expanded in which you need to search for the select “USB host controller” . Usually, it has a longer name on each PC but it necessarily includes these three words.
- If you do not get this option, the USB port is presenting a failure . To fix it, click on the “ Search for hardware changes ” button at the top.
- After that, you will start a verification procedure that should detect it and any connected device .
- Next, if the port still does not work, you must reinstall its drivers and to do so, click on the host controller elements USB, for now uninstall each of them .
- Once uninstalled, you need to restart your computer and so, the drivers will be reinstalled from automatically Finally, must solve problems or damage to the USB port .
Disable the USB selective suspend function
The selective USB suspension is an energy-saving setting that has the ability to reduce the use of a laptop’s battery , through a kind of “ cut > ”In the device power.
However, by having this function activated on your computer, you can override the USB driver of the device and in that way, will negatively affect the operation of external devices , since no way can detect it .
In this sense, it is possible to conclude that although it is a function that generates good benefits and works very well, it causes inconveniences around the operation of the USB ports of the computer .
To solve it, you must execute the following step by step:
- On Windows, access the “ Control Panel ” menu by simply typing those words in the search bar on the computer’s start bar and choosing the option that shows you .
- After that, go to “ Hardware and sound ”, where a series of selections will appear and you have to click on the one identified as “ Energy options ”; located in the fourth position.
- When you are already in “ Energy options ”, click on “ Choose or customize a power plan ”And then click on“ Change plan settings ”.
- Then, select“ Change advanced power settings ”. Since then a new window will open and there, look for “ USB Settings ” where they show you an option called “ Selective USB Suspend Settings ” that will surely be activated and you must change in the drop-down menu to “ Disabled ”.
- Finally, click on the “Apply” button and then on “ Accept ”to confirm the action. Now, restart your computer and with it, your peripheral should work normally .
