Universal Serial Bus (USB)
is a connectivity specification developed by the USB
Implementers Forum. USB is aimed at peripherals
connecting outside the computer in order to eliminate
the hassle of opening the computer case for installing
cards needed for certain devices. USB provides for ease
of use, expandability, and speed for the end
user.
USB 2.0 drivers for Intel® motherboards are
available on the Intel
developer site for your motherboard. Some
motherboards also include drivers on the motherboard
software and drivers CD.
Intel® 82801DB I/O Controller Hub (ICH4)
or newer Intel chipsets utilizing the
Intel® 82801DB I/O controller hub (ICH4) or newer
support USB 2.0. The Intel®
Chipset Identification utility can determine if
your system has this I/O controller hub.

device does not ship with Windows 98 drivers,
contact your device or system manufacturer. If
USB 2.0 drivers are not available, your device
will operate at USB 1.1 speeds

USB 2.0
support is available in kernel 2.4.19† or later development kernels, or in
the 2.4.19 or later production kernel. More
information.
Third
Party USB Controllers Some motherboards use
a USB controller chip from a third party, such as NEC*.
Drivers for the USB controller should be provided by the
system or motherboard manufacturer. Please refer to the
USB Resources and Documentation area below for more
information.
USB 1.1
USB Driver Update (for USB 1.1 and
earlier): Recent versions of most operating
systems (including Windows 98, Me, 2000, XP, and Linux*)
include fully functional drivers for the USB port of
Intel® chipsets. In order for Device Manager to show
what USB controller is in the system, the chipset must
be recognized by the operating system. Some systems
require the Intel®
Chipset Software Installation Utility in order for
the operating system to fully recognize the chipset. Do
I Need the Intel® Chipset Software Installation
Utility?
Note: There are no
separate USB (version 1.1 and earlier) drivers available
for download for Intel® chipsets.
Troubleshooting
If the manufacturer/vendor of a USB device
recommends downloading an Intel® USB driver update as
part of troubleshooting your USB device, please contact
Microsoft* for USB driver support. Intel manufactures
the host controller but the driver is from Microsoft.
While the Intel Chipset Software Installation Utility
provides functionality, it will not install
updated USB drivers; these are available from
Microsoft.
For further troubleshooting, contact
the USB device manufacturer.
