Plug-and-play devices include keyboards, external hard drives and other hardware that can simply be plugged into your computer and will work without manually installing software. You can update the driver used for a plug-and-play device to fix issues that you are experiencing with the device or if you want to use the newest version of the software. Device Manager can be used to search for a newer version or you can select the driver from a list or a location on your computer. Tips Writer Bio
