How to Install USB 2.0 Drivers on a PC
USB 2.0 drivers are used to connect external storage devices, such as external hard drives and flash drives, to a computer through USB ports. Some versions of Windows, such as XP, do not come with USB 2.0 drivers installed on the system. Without these drivers, devices plugged into the USB ports do not operate properly. To be able to operate the devices, you must download and install the USB 2.0 drivers for your PC.
Download a Windows Service Pack from Microsoft's website (see Resources). Windows Service Packs are offered for nearly all Microsoft Windows operating systems and contain USB 2.0 drivers for systems that do not already have them installed, as well as updates for systems that do have USB 2.0 drivers installed. Service Packs are listed by system on the Microsoft Download page.
Install the Windows Service Pack that you have downloaded to your computer. To install the Service Pack, go to the "Downloads" folder of your computer, double-click the Windows Service Pack icon. The "Software Update Installation Wizard" screen opens.
Click "Next" on the first page of the "Software Update Installation Wizard" screen and follow the on-screen directions to install the Windows Service Pack onto your system. Press the "Finish" button when you are on the last page.
Choose "Yes" to restart the computer if you are prompted to do so. Some operating system versions will restart automatically and do not ask permission.
Open the "Start" menu on your computer by clicking the "Start" orb or "Start" button, depending on your version of Windows. Choose "Control Panel" and go to "System Tools" or "Hardware and Sound," then click "Device Manager."
Go to the "Tools" menu if the devices are not automatically listed by type, such as "Disk Drives" and "Keyboards." Expand the "Universal Serial Bus Controllers" section and look for a device that starts with "USB 2.0." If it isn't in the "Universal Serial Bus Controllers" section, expand "Other Devices" and look in that section. When you locate the "USB 2.0" device, right-click on it and choose "Update Driver" from the list of options that appear.
Press the button to "Install the software automatically." Click "Next" and the USB 2.0 drivers are installed on your computer. Once the drivers are done installing, a final screen comes up. Click the "Finish" button to close the windows.
