Universal Serial Bus (USB) connections have opened the door to hardware becoming more mobile. Both wired and wireless network cards can come in the form of a USB adaptor, as can sound cards and various disk drives. The installation of these devices is typically straightforward. This depends on the maker of the hardware, however; lesser known brands may require you to manually download the drivers, or use the disc that came with the hardware.

Skill level:
Moderately Easy


  1. 1

    Power on your computer and log in to your operating system.

  2. 2

    Plug in your USB device. You should see a notification that drivers are being installed. Check to see if the network card hasn't already been installed (if you don't see a notification) by opening "Control Panel" from your "Start" menu.

  3. 3

    Click the "Network and Sharing Center" icon.

  4. 4

    Select "Change adaptor settings" from the menu. You should see the name of your USB network card if it's been installed. If not, you'll need to check for drivers using "Windows Update."

  5. 5

    Open your "Start" menu and click "All Programs."

  6. 6

    Click "Windows Update" and then "Check for updates." The drivers for the hardware should be found; you can click the corresponding link to see them. Check them off and click "OK."

  7. 7

    Click "Install Updates." The program will inform you when it's finished.

Tips and warnings

  • The device drivers are typically on a disc that comes with the hardware.
  • You can download drivers from the manufacturer's website. Carefully examine the adaptor; it should have the make and model listed.
