Fixing the problem of disconnecting and connecting USB of computer and laptop

It can be annoying when a USB flash drive is connected to a computer, and the connection is repeatedly disconnected and reconnected. Many people in this situation are looking for a solution to fix this problem. But what is the reason for disconnecting and connecting the USB port? Join us to learn how to solve the problem of connecting and disconnecting the USB of a computer and laptop.

Introduction

You may have suddenly heard the short sound of the external drive disconnecting in Windows when you have nothing to do with the drive connected to your system. After a few minutes, the system speakers play the sound of its reconnection. These two back-and-forth sounds are the most common in working with USB drives. We may have all experienced it well. Occasionally, this mode may remain in one of the two back-and-forth sounds, and Windows does not play the disconnection and connection sound. For example, you hear the sound of the drive disconnecting, and the connecting sound is no longer heard. You have to connect the USB stick again and manually remove and re-insert the drive to access the data content inside.

The problem of disconnecting and connecting USB can have several reasons in software or hardware. Under the influence of these factors, sometimes the user can get into trouble or even cause the loss of important information while working with the data in the flash drive. USBbecome Therefore, it is necessary to know the causes of these problems and propose solutions. This article will discuss the software and hardware causes of USB connection and disconnection, check the flash drive, and provide ways to fix these problems. Stay with us in the future.

The reason for disconnecting and connecting the USB port

As we said in the introduction, connecting any USB device and a flash drive may cause problems and instability for various reasons. When connected to the system, it is constantly disconnected and connected. The reasons for this can be divided into software and hardware. In the following, we will examine both categories.

Hardware causes of disconnection and connection of USB drive

Hardware causes related to failure or damage of physical USB components and flash drives that can cause the USB drive to be disconnected and connected work. These causes can include the following:

Failure in the USB port or cable

USB ports or cables may be broken or damaged due to excessive use, impact, dust, moisture, or other factors. This error can cause the connection between the computer and the device connected to the USB port to be unstable and generally not secure. For example, suppose the USB port or cable is broken. In that case, it may cause electrical or magnetic interference and disconnect and connect without the user’s hand due to pressure on some bases.

Failure in the flash drive body or switch

Like the cable or the port itself, the body or switch of the flash drive may also be damaged due to the same reasons (i.e., pressure, heat, cold, or other factors). This error can cause an improperly inserted flash drive into the USB port that is not set or in Write Protection mode. For example, suppose the body or switch of the flash drive is cracked or broken. In that case, it may cause the connection between the board and the flash drive chip to be lost or the connection to be unreliable with the slightest shock from external factors.

Failure in the flash drive board or chip

The flash drive board or chip may be damaged due to a short circuit, excessive pressure, burn, or other factors. This, in turn, can cause the flash drive not to be recognized by the computer, and a secure connection between it and the USB port cannot be made quickly. For example, suppose the flash drive board or chip comes into contact with water or other liquids. In that case, this may cause corrosion or oxidation of the pins or internal connectors, resulting in a permanent connection to the USB port. The system will become unstable, resulting in the simultaneous disconnection and connection of the port during connection.

Software causes sudden disconnection and connection of the USB drive.

Contrary to popular belief, the appearance of disconnecting and connecting the USB drive for no apparent reason is only sometimes hardware-related. In fact, due to software reasons and operating system problems, the mentioned mode is created. While working with the system, the sound of the USB drive disconnecting and connecting is constantly heard. In this situation, it is most likely that one of the following can cause the USB device to disconnect and connect combined to the system:

Viruses and malware

If your USB or flash drive is infected with a virus or malware, it may cause problems connecting it to the computer. Some viruses and malware can hide the flash drive and the drive ID(Drive Letter), modify, delete, or rename existing files, or prevent data from being written or read. For example, the Shortcut virus is one of the most common viruses that attack flash drives. This virus turns all the files on the flash drive into shortcuts and makes them inaccessible.

Incompatible or outdated drivers

Drivers are software that helps the operating system communicate with different hardware. USB drivers are responsible for connecting the computer with USB flash drives. Suppose these drivers are incompatible with your operating system version or are not up to date. In that case, they may cause problems with USB detection and connection. And flash drive. For example, if you use Windows 10 but USB drivers are designed for Windows 7, it may cause interference, a USB connection, and a disconnection and flash drive. Of course, it is less common because Windows automatically updates many frequently used drivers. Still, it may also be seen in some old versions of Windows or driver installation from unreliable sources.

Power management settings

Some operating system settings can negatively affect USB performance and have a flash drive. For example, Power Management settings can cause the operating system to save power and USB ports to turn off.

Registry settings or disk management

In addition to the above, Registry settings can cause the flash drive to be in Write Protection mode and prevent data from being written or deleted. Disk Management settings can cause the flash drive’s drive letter to interfere with another drive and prevent it from being recognized.
