USB is unique because it is Plug-and-Play, which
allows a computer to instantly recognize when a
device like a keyboard, mouse, or scanner has
been connected to it. Once the device has been
recognized, it’s ready to go. No special setup is
required. Similarly, USB supports hot swapping -
- the insertion or removal of devices while the
computer is turned on. You can swap one device
for another without having to power down your
system or install any special software -- it really is
that easy.
Another unique USB feature is its ability to allow
multiple devices to be connected to a computer’s
single USB port. When used in conjunction with a
USB Hub, like the Linksys USB 4-Port Hub, mul-
tiple devices can operate simultaneously and inde-
pendent of each other, allowing easy access to an
enormous array of different devices at the same
time. Hubs and devices can be connected together
-- you can connect up to 127 devices to a PC’s
USB port.
Some of the devices that USB supports include
digital cameras and scanners, joysticks, gamepads,
keyboards, hard drives, mice, modems, phones,
printers, speakers, and more.
