Ever wondered why your computer desk has holes in it? The LINDY In-Desk USB Hub fits neatly into your desks pre-cut holes and connects easily to your computer to provide an extra 4 USB 2.0 ports. The clever design keeps your desk clutter down to a minimum whilst still giving you quick and easy access to USB ports. The main body of the hub can be removed from its outer ring to aide installation. This outer ring can then be used for cable management as well as the hub\'s home. The USB In-Desk Hub is perfect for use with USB storage devices and USB cables to connect your peripherals. * Note: This hub is bus powered - it takes its power from the computer\'s USB port. You can use it with both bus-powered USB devices (e.g keyboards, pen drives, MP3 players) and self-powered USB devices (e.g. printers and external hard drives with their own power supplies). When used with bus-powered peripherals it can support 4 devices with a total power consumption of up to 500mA.
