In this article, we will explain what USB 2.0 is, why you need a driver, how to check if you have it, how to download and install it, and how to troubleshoot any issues that may arise.
What is USB 2.0 and why do you need a driver?
USB stands for Universal Serial Bus, and it is a technology that allows multiple devices to connect and communicate with a computer through a single port.

USB 2.0 features and benefits
Higher data transfer speed: USB 2.0 can support up to 480 Mbps (megabits per second), which is 40 times faster than USB 1.x.
More power delivery: USB 2.0 can provide up to 500 mA (milliamps) of current to each device, which is enough to charge most smartphones and tablets.
More device support: USB 2.0 can handle up to 127 devices per port, while USB 1.x can only handle up to four.
Backward compatibility: USB 2.0 devices can work with USB 1.x ports and vice versa, although at a reduced speed and functionality.
A driver is a software program that enables the communication between a device and the operating system of a computer. It acts as a translator that converts the commands and data from the device into a format that the computer can understand, and vice versa. Without a driver, the device will not function properly or at all.

How to check if you have USB 2.0 on your computer
If you want to use USB 2.0 devices on your computer, you need to make sure that your computer has a USB 2.0 port and a USB 2.0 controller driver installed. There are two ways to check this:
Using Windows Explorer
Open Windows Explorer by pressing Windows + E keys on your keyboard.
Right-click on My Computer. Select Properties from the menu.
Click on the Hardware tab.
Click on the Device Manager button.
Expand the Universal Serial Bus controllers category.
Look for any entries that have USB 2.0, Enhanced, or EHCI in their names. These indicate that you have a USB 2.0 port and driver on your computer.
Using Device Manager
Open Device Manager by pressing Windows + R keys on your keyboard, typing devmgmt.msc, and clicking OK.
Expand the Universal Serial Bus controllers category.
Look for any entries that have USB 2.0, Enhanced, or EHCI in their names. These indicate that you have a USB 2.0 port and driver on your computer.
How to download and install USB 2.0 driver for Windows
If you do not have a USB 2.0 driver on your computer, or if your existing driver is outdated or corrupted, you need to download and install a new one. There are three ways to do this:
Using the Drivers and Utilities CD from Dell
If you have a Dell computer, you can use the Drivers and Utilities CD that came with your computer to install the USB 2.0 driver. Here are the steps:
Insert the CD into your CD-ROM drive.
Follow the instructions on the screen to launch the CD menu.
Select Dell Drivers and Utilities.
Select Your System Model.

Restart your computer when prompted.
Using the Windows Driver Kit from Microsoft
If you have a non-Dell computer, or if you do not have the Drivers and Utilities CD, you can use the Windows Driver Kit (WDK) from Microsoft to install the USB 2.0 driver. The WDK is a collection of tools and drivers that can help you develop, test, and deploy drivers for Windows. Here are the steps:
Download the WDK from [this link].
Select the version of Windows that matches your operating system.
Select EWDK with Visual Studio Build Tools.
Select Create download package.
Select a location to save the package and click Create package.
Extract the package to a folder on your computer.
Navigate to the folder and double-click on EWDKLaunch.cmd.
A command prompt window will open. Type bcdedit /set testsigning on and press Enter. This will enable test mode on your computer, which allows you to install unsigned drivers.
Type bcdedit /set nointegritychecks on and press Enter. This will disable integrity checks on your computer, which prevents Windows from blocking drivers that are not digitally signed by Microsoft.
Type bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS and press Enter. This will disable driver signature enforcement on your computer, which allows you to install drivers that are not verified by Microsoft.
Type bcdedit /set loadoptions ENABLE_INTEGRITY_CHECKS /nointegritychecks off /testsigning off /debug off /osdevice partition=C:. This will restore the default settings of your computer after installing the driver.
Type bcdedit /enum all > bcd.txt & notepad bcd.txt & exit . This will create a text file with your current boot configuration data and open it in Notepad.
In Notepad, look for a line that says windowsbootloadersettingsidentifier current . Copy the value of the identifier, which should look something like xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.
Close Notepad and go back to the command prompt window.
Type bcdedit /set identifier testsigning on and press Enter. Replace identifier with the value you copied from Notepad. This will enable test mode for your current Windows boot loader.
Type bcdedit /set identifier nointegritychecks on and press Enter. This will disable integrity checks for your current Windows boot loader.
Type bcdedit /set identifier loadoptions DDISABLE_INTEGRITY_CHECKS and press Enter. This will disable driver signature enforcement for your current Windows boot loader.
Type exit and press Enter. This will close the command prompt window.
Restart your computer.
After restarting, navigate to the folder where you extracted the WDK package.
Open the folder named x86 if you have a 32-bit operating system, or the folder named x64 if you have a 64-bit operating system.
Open the folder named usb2.0.
Right-click on the file named Ehci.inf and select Install.
Follow the instructions on the screen to complete the installation.
Restart your computer again.
Using the official website of your device manufacturer
If you have a specific USB 2.0 device that you want to use on your computer, such as a printer, scanner, camera, etc., you can also download and install the USB 2.0 driver from the official website of your device manufacturer. Here are the general steps:
Go to the official website of your device manufacturer.
Find the support or download section of the website.
