This 4-port USB hub is the ideal companion for your laptop or desktop computer. It allows simultaneous operation of up to four separate devices all attached to a single USB port. The octopus-like extensions are great for bulky USB devices, such as thumb drives and card readers, that don't work with standard USB hubs. The design also helps to eliminate cable clutter. This hub is perfect for use with all USB 1.1 and USB 2.0 peripheral devices.
