USB technology came to revolutionize the world of computing , which was long in search of a connector that would be the standard worldwide, so as not to have incompatibility problems in electronic equipment. Also, USB technology has come a long way over the years, so the difference between USB version 2.0 and 3.0 is abysmal in terms of speed.

How to enable the USB ports of a computer
Enabling the USB ports of a computer is not a difficult operation to perform, but you must know the steps you must follow to do so. To carry out the enablement on PC with Windows operating system there are several ways to do it and then we will show you them.
The first way to enable the USB ports of your PC will be through the Windows registry editor . The steps are as follows, go directly to the Windows icon that is in the lower left. By clicking you will enter the ‘Start Menu’. In the search box you are going to type ‘run’.
You can also use the keyboard shortcuts to access the search box and for this you just have to press the Windows + R keys. The Run box will appear on the screen and in it you must type the command ‘regedit’ and ‘then OK’ . The next step is to follow the following sequence HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Services / USBSTOR.
In the box on the right you must click on the ‘Start’ option and a small box will appear and you will write in the ‘Value number’ section 3. And in the Base section you will select the Hexadecimal option and finally click in the OK option. To finish enabling the USB ports, you must close the open windows and restart your PC.
We will show you another way to do it if this seems a bit confusing, the first thing you are going to do is use the keyboard shortcuts. Then press the Windows + X keys, this action will generate a contextual menu on the screen and from which you will choose the option ‘Device Manager’, although you can follow this path Start> Control Panel> Hardware and Sound> Device Manager .
The next step is to select the option ‘ Universal serial bus controllers ‘ from the list, now you must look for the option that is displayed with an exclamation point. Position yourself on this option with the mouse and right click. A menu of options will be displayed and you will select the option ‘Enable device’ and list you have enabled the USB ports.
What are the main reasons why my USB port is not working properly?
Once we have enabled the USB ports of our personal computer or laptop, it may still not work properly . And this can have different causes that we will analyze below.
Dirty or damaged USB input
The USB ports , being exposed to the environment, tend to fill with dirt, which can obstruct the entrance of the cable that we are connected to, so you can periodically clean them, using compressed air. Although later we will explain how to carry out this procedure correctly.
Another reason why you may have problems with a USB port is the poor connection of a USB extension , since these are designed to lengthen or take the USB connection to difficult places , this is done through a cable that connects to any of the ports. But if these are misused or have a poor connection, it may appear that the port is down.
Finally and a little less frequently, your USB port may have been burned or physically damaged, if this is the case, you will not be able to connect any device and you will have to use a ‘Hub’ to expand another port . This usually happens when we try to draw electricity from the USB port and it is not done correctly.
Malware or virus on your computer
One more reason why USB ports can be affected is by a virus that disables their controller , so it is important to be careful what memories we put in our PC, since these viruses are generally difficult to eliminate. If you have an antivirus program you can do a scan to rule out this option.
Error code 43
There is another problem that can prevent the USB ports from working properly or simply generate an error code. As is the case with code 43, which indicates that the USB port is not recognized by Windows . Although this code also usually appears when we connect an external disk, graphics card or any other device connected by this means.
Outdated driver or driver
One reason why the USB connection in any of the ports of your computer may be disabled is that it has a problem with the drivers that control it, so you should always verify that they are updated and enabled. But later we will show you how to correctly update the drivers.
For this we must stop on the start menu icon and right-click , a list with several options will appear, where we must look for one that says ‘devices’ and click on it. Then we will load a window in which we will have all the devices installed, from the video ones to the audio ones.
If we look closely, we will also find those intended to control the USB ports. If we right-click it, we may notice that there is an option to check for updates to the driver. In the same way, we will have the option to both disable and enable.
If on the other hand it is enabled, then we can try looking for updates, this can also help us in case we have USB that works slowly. As a last alternative, we can try to restart our computer, because this can help us so that if the problem was a controller, it will load again and any type of error is eliminated.
What can I do to make my USB input work normally?
As we have seen, there are various causes that cause a USB port to malfunction . But best of all, most of the solutions to these problems can be applied ourselves and without major complications. So let’s see then what are the possible corrections that we can carry out.
Reboot your pc
One of the first solutions that we can carry out that corrects problems with drivers or software to a high degree is by restarting the computer . Although it may seem very simple, it is usually a very effective way to troubleshoot USB device recognition.
Clean your USB port
As we already mentioned, a dirty USB port, full of dust or that shows the presence of some type of substance that prevents a correct coupling. It can be a very recurring cause of failure of these connectors. Therefore you can use a blower to help remove the dust or use a cloth moistened with alcohol to clean its contacts.
Replace your USB input
In the event that the problem is due to a damaged USB port, it will be necessary to replace it with a new one. And in these cases, unless you know how to remove and solder the USB port that does not work. You are going to have to take your computer to technical service so that they can replace the USB port or, failing that, the motherboard .
Restore your PC’s operating system
Another solution that we can use is to restore the system to a date when the USB ports worked without problem . Since due to a present conflict, it will not allow the ports to work in the way they did previously. To apply this corrective go to ‘Start’ then select the option ‘All Programs’ and then click on ‘Accessories’.
Now you must choose the option ‘System Tools’ and finally select ‘Restore systems’. Now simply select the most recent date and where you knew the USB ports worked smoothly. Follow the wizard’s prompts and wait for the process to complete.
Before finishing we will give you a last alternative that you can apply if the previous solutions did not offer you positive results. And it is about freeing your PC from all electrical energy and in this way the USB port can be put into operation.
The correct way to do this is the following, first we must send to turn off the equipment. Once it is off, we must completely disconnect it from the electrical current, so that there is no way for electricity to enter it, in case of using a laptop , we must also remove the battery.
Then we must press the button with which we turn it on for about 10 seconds , this will cause the internal components to discharge, and that they can obtain new and clean current. This can also help us in cases where they are overloaded or have static.
Once we complete this, we can reconnect everything and turn on our equipment, if everything has gone well, you should no longer have problems using any of your USB ports.
