USB controller
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
If
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.
Note:
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.
