When you have the correct type of USB cable to hand, plug it first into your laptop and then into your desktop PC. The operating systems (typically Windows) on both devices should detect the USB connections and install the required drivers to allow you to then send data or files from one device to the other. Note that you may need to use Windows Update to find the right drivers if you’re using an older version of Windows.
With a connection from your laptop to your desktop PC established via USB, files and folders can be transferred and even the Internet connection can be shared. Although USB Bridge cables can provide a solution to this sort of linkup on devices running USB 1.1, a better result for data transfer can be achieved with devices equipped with USB 2.0 – USB 1.1 is limited to data transfer rates of 12 Mbps (1.5 Mbps on some devices) while USB 2.0 can transfer data at 480 Mbps.
