Many laptops (especially the older ones) have only one built-in USB port, and don't allow you to multi-task with several peripherals. Here's a stylish solution. This laptop hub expands your USB configuration and provides three extra ports for connecting peripherals. Ideal for keyboards, mice and other low-powered USB devices. Small, lightweight and portable, it just stores in your laptop's case or pocket. With a transfer rate up to 480 Mbps, it's fully USB 2.0 compliant and compatible with all USB peripherals, and USB-enabled PCs and Mac®s. Because it's bus-powered, there is no need for an additional power supply. Plus, the LED indicator on the cable shows when your hub is being powered, while the flip-up plastic cover protects your ports when not in use. Provides four A device ports, with one upstream port. No software required.
