USB stands for Universal Serial Bus, a very common computer connection. USB comes in v1.1 and v2.0, which is approximately 40x faster, and even faster USB 3.0 devices will appear in 2010. Most desktops and laptops have several USB ports as there are many peripherals and devices that use USB. If necessary, more USB connections can be added with an inexpensive USB hub. If using a USB hub, some devices such as scanners take their power from the USB connection. A hub may not be able to push out enough power unless you have a powered hub that plugs into the mains.
