USB

Defining the USB and solving all problems related to its Ports is what we will address in this post.

Dear visitors, followers and fans of the blog of the Electronics Professional Space. And I will make this topic, God willing, a topic that enriches the knowledge of everyone who read it about USB.

Certainly, dear reader, some questions have begun to come to your mind and you hope that the topic will be covered until your understanding of the USB is complete. These questions may be of this type: What is the solution to the problem of the computer not recognizing a USB device ?, What is the meaning of a USB connection or a USB connection What about USB and Wi-Fi? What is the solution to the problem of defining a USB device? Simply what is the definition of a USB? What are the best types of flash drives or the best types of USB ?, What Usb port and usb cable connection? And other questions.

Just follow up with me and you will have a full answer to all your questions, God willing. Without me being too long, we start the topic on the blessing of God.

Let's start first by learning about the characteristics and features of the USB port, or the so-called USB port.

USB features and features

 A large number of electronic devices can be connected to the computer that works as a host computer, either through the USB port or through other ports such as a VGA port, a DVI port, or many other ports. With regard to the speed of data transfer between external devices and the USB ports, it may reach about 400 megabytes per second, and that is in the USB 2.0 port, which means twice the data transfer speed on USB 1.0.

USB Connector

The USB port or the USB 2.0 cable contains four pin or simply four wires. Two power wires, which are +5 volts and ground, and two other data wires for data transmission, which are + D and -D, while in the USB version of USB 3.0, other wires were added to transfer data. Thus, USB 2.0 can only send data in one direction, as for the USB With USB 3.0, it can transfer data in both directions simultaneously.

 Among the advantages of a USB connection or a USB port in general is that USB devices can be connected to the computer and disconnected at any time, which means that they are exchangeable without any problems, and this feature is called Removable in English. Many USB devices can be switched to sleep or sleep mode via BIOS settings in order to save energy.

USB types

USB-A

 Typically used with mouse and keyboards.

USB-B

It can be found not only on computers but also in printers, game consoles and other regular electronic devices

Micro USB

This type is simply a synonym for the first two types, namely:

USB-A and USB-B.

USB Type C

This type of USB is designed to replace Micro USB, and what distinguishes it most is its smaller port and support for more devices.

USB 1.1

It was released in late 1998, and it was the first USB version that received wide attention, its speed could reach nearly 10 megabytes per second.

USB 2.0

It was released two years after the release of USB 1.1

Its speed reaches nearly 400 mbps.

USB 3.0

It was released in 2008, and it is characterized by faster speed compared to USB 2.0, speed may reach 4 GB per second, and the port is colored in blue.It should be noted here that the two ports, USB 3.0 and USB 2.0 are compatible in another term, you can use a USB key or a flash memory with a feature USB 2.0 with USB 3.0 port without problems.

USB 3.1

It was released 5 years after the release of USB 3.0

Its speed is estimated to be twice that of USB 3.0, at approximately 8 or 10 GB per second.

Thus, we completed the first part of the topic, which included the definition of USB / USB port / USB cable, types of flash drives or types of USB and other points.

Now we move on to the second and most important part, in which we will deal with ways to solve the problem of USB ports, and of course I deliberately arranged this, meaning we started with the definition and mentioned the types of USB first, and then addressed the solution to its own problems, in order to facilitate understanding and understanding the topic optimally.

Ways to solve problems with USB ports

The USB port and the USB connection are indispensable in these days, as almost all devices contain USB ports, but most of these port technologies have all switched to using the USB port, for example, mouse, keyboard or keyboard, printer, hard disk External, external disk reader, flash memory and other devices that use the USB port instead of the first ports, which were large and slow in terms of data transfer. And because it is, to speak, the main means of transferring data on the motherboard, so the issue of a malfunction in one of the USB ports on the laptop in particular is a difficult and annoying issue, so it needs to be repaired in various ways so that the work on the laptop returns to its normal state where you cannot imagine a laptop Without the USB ports, so below we will see the solution to the most important problems that you may face in the USB ports on your laptop.

Of course, it is worth noting that you should not start any repair process on any USB port until you are honestly sure that the problem is from the port and not from the external device linked to the USB port. Here is a way to ensure that there is an explicit malfunction of the USB port: by using a flash memory on the computer To be sure of its outlets, we do the following: Connect the flash memory to the computer and note. We consider the flash memory to be unrecognized or not read. Connect it to another computer and note the result, if it is identified, this is an explicit evidence of a problem in the port of the first computer, but if the second computer in the experiment did not recognize it, this is definitely due to the damage of the USB and not On the computer, please focus on this point before making any decisions regarding maintenance.

So if we make sure that the problem is from the USB port, you only have to apply the following:

- Verify that the USB Driver is enabled on the device

Check the activation of the USB port of your computer, because sometimes, for unknown reasons, that driver may be disabled after installing a program or driver on your device. Therefore, you must verify that all ports on your computer are activated and that the Windows operating system recognizes them all.

 The method is easy and it is as follows: Press the Windows button on the keyboard + the letter R, type the following command: devmgmt.msc, which means Device managment, which means device management in the Run window and press Enter. Then the Device Manager window will appear. Click on the arrow next to Universal Serial Bus controllers and ensure that all USB drivers are enabled. If you find that the USB port is not activated, do not worry, you only have to click on it with the right click of the mouse and then choose the Enable device to enable it. Congratulations.

But in the event that you find that all the ports are activated, but a defective identification problem appears, then you must remove the definition of the USB ports to be redefined again and thus solve the problem of the computer not recognizing the usb device.

For reference only to an important point that many overlooks, which is that the second generation USB 2.0 ports are self-installing, meaning that the Windows system is the one that takes care of it automatically and is ready to work directly after installing Windows, while the third generation 3.0 ports need you, as a user, to install the definition Own from the manufacturer's website.

 Discharge of static electricity or static energy

Concerning the discharging of static electricity, a separate topic has been devoted to the Code, and its principle is: The problem of disrupting USB ports can be fixed by eliminating static electricity on the electronic components of the motherboard of a laptop, by following the following steps: remove the laptop battery, then remove the power cable For AC. Pressing the POWER BUTTON for about 20 seconds. Reconnect the laptop to the AC power cable, and press the power button normally, then you will have eliminated the excess and harmful static electricity for electronic devices.

To know more about static electricity or static energy, see this topic that will benefit you greatly:

The computer does not boot and the screen is black - the solution

Among the known problems that happen a lot, especially when it comes to the USB cable, is the instability of the cable to the USB port, due to its extensive use so that it becomes incompatible with the port and thus the problem of the computer not recognizing the USB device

Or the problem of the definition of usb device and other faults.

The USB port was down due to a short circuit problem

The occurrence of a short in the USB port is one of the most difficult problems that may occur on the laptop, as the short circuit may not result in damage to the port alone, but rather the matter may lead to damage to the southern chipset or the southern bridge, and thus a near total failure of the motherboard. In order to avoid the problem of the short, you should pay attention to the ports When inserting the USB cable of a device.

So, my dear ones, who follow the blog of the electronic professional space, we will have completed our interesting topic, which I sincerely hope you will like, and of course, for those who want to enrich their information, you will have some questions that may help you search on Internet pages without wasting much time and effort.
