Question about PC Desktops
UNIVERSAL SERIAL BUS(USB) - is the most common type of computer port used in today's computers. It can be used to connect keyboards, mice, game controllers, printers, scanners, digital cameras, and removable media drives, just to name a few. With the help of a few USB hubs, you can connect up to 127 peripherals to a single USB port and use them all at once (though that would require quite a bit of dexterity).
USB is also faster than older ports, such as serial and parallel ports. The USB 1.1 specification supports data transfer rates of up to 12Mb/sec and USB 2.0 has a maximum transfer rate of 480 Mbps. Though USB was introduced in 1997, the technology didn't really take off until the introduction of the Apple iMac (in late 1998) which used USB ports exclusively. It is somewhat ironic, considering USB was created and designed by Intel, Compaq, Digital, and IBM. Over the past few years, USB has become a widely-used cross-platform interface for both Macs and PCs.

Although many computers
have an integrated USB controller on the motherboard, many computers may
also have an expansion USB controller card. If your USB connectors are
not connected directly to the motherboard it is likely your computer is
using an expansion card.
Motherboard USB controller
your USB controller is integrated on the motherboard it is generally
best to consult the motherboard documentation or visit the motherboard manufacturer's web page for online documentation regarding your USB controller.
Expansion card USB controller
If your USB controller is an expansion card it would be best to refer to the manufacturer's documentation or visit the manufacturer's web page for additional information about your USB controller.
If your USB controller is currently installed and working and you are
running Microsoft Windows 98, Windows ME, Windows 2000, or Windows XP,
you can determine the USB controller currently installed by opening the
Universal Serial Bus controllers category in Device Manager. For example, "SiS 7001 PCI to USB Open Host Controller" indicates a computer is using the SiS chipset.
