USB Expansion Cards

USB expansion cards, also known as USB adapter cards, are devices that provide additional USB ports to a computer. These cards are particularly useful when the computer has a limited number of built-in USB ports, or the existing ports are inaccessible or difficult to reach. USB expansion cards are installed into an available expansion slot on the computer’s motherboard, and once installed, they allow for connections of multiple USB-enabled devices such as keyboards, mice, printers or external hard drives.
