Universal Serial Bus (USB) is a standards-based, external serial bus for the computer. USB is universal in that many types of peripheral devices can be connected to a computer by plugging them into USB ports, using standard USB cables, connectors, and sockets. USB fully supports Plug and Play, which means peripheral devices can be plugged in and unplugged while the computer is running. The operating system immediately detects a device that is plugged in and tries to load device drivers for the device. USB hubs can be used to connect several devices to one computer. A hub provides multiple USB ports for Plug and Play devices. The hub is then plugged into the computer, directly or through another hub, using a single USB cable. Windows XP Professional has built-in support for many USB devices. (See USB Devices later in this chapter.) When a user plugs in a USB device for which Windows XP Professional does not have built-in support, a dialog box is displayed that allows the user to manually point the Plug and Play subsystem to the location of the device drivers for that device (typically independent hardware vendor [IHV] provided drivers on a floppy disk or CD-ROM). USB has the following advantages:

All USB devices connect to the computer by using either the standard USB port or an A connector. A USB controller supports up to 127 devices. Hubs are used to obtain ports in addition to those supported by the root hub. USB supports hot plugging plugging in or unplugging a USB device while the computer is running. USB supports the selective suspend feature, which allows USB device drivers to selectively shut down their devices when they detect that the devices are idle. When the device is put back in use, such as when a user moves a USB mouse, the driver turns the device back on. This is particularly important for power management of mobile computers.

As illustrated in Figure 9-2, USB uses a tiered topology so that you can simultaneously attach up to 127 devices to the bus. USB supports up to seven tiers, including the root tier and five nonroot hubs. The lowest tier supports only a single nonhub device. Under the USB specification, each device can be located up to 5 meters from the hub or port it is connected to.
