Microsoft USB 2.0 Driver Information
The latest version of Microsoft USB 2.0 driver
stack is included in Service Pack 1. The stand alone drivers have been
pulled from both the Windows Update Site and the Corporate Download Site.
Service Pack 1 is available at the Microsoft
Windows
Update Site.
The easiest and surest way to use these drivers
is to allow Windows Update to install them automatically.

XP USB 2.0 drivers

support for Windows XP is available

Alternatives
Many USB 2.0 card manufacturers
have developed USB 2.0 drivers for Win98 SE, ME and Win2000.
Although,
all PCI/USB cards are currently using the same NEC µPD720120GC-9EU,
the drivers are by and large proprietary and only function with the
branded USB2.0/PCI card that the
drivers are written for. In other words, the drivers obtained from
Keyspan will NOT work with an
Adaptec card and vice versa.
If you plan to use USB 2.0 with Windows 98SE
and ME and your older motherboard, your only option is to purchase a card from a manufacturer
that supplies the drivers for your OS.

Linus Torvalds, creator and
head of the Linux operating-system project, released the 2.5.2 Kernel on
Monday, January 14, 2002. The new 2.5.2 software core, in addition
to other improvements, contains support for USB High-Speed (USB
2.0). If you know what all this means, you likely don't need a
lengthy explanation of the purpose and use of the new kernel.
Additional information and links can be found on the
Linux
USB page.

The Logo
The
new USB 2.0 logo
The new logo can only be displayed on products
that have passed USB-IF certification testing.
Why buy Certified? High Speed Certification
means the device has demonstrated compliance and function in accordance with
the USB 2.0 standard. It also means the maker was willing to pay the money
and take the time to have his device tested and approved. With literally
every small village in China making USB devices these days, it's easy to be
fooled by the lower priced, look alike, knock offs that proliferate the
market place. There's a lot of junk out there. The difference between the
good and the rest is usually only a couple of dollars.

USB 2.0 Background
-
To further increase I/O bandwidth and the range of
peripheral applications, the USB 2.0 Promoter Group - lead by Intel and six
other high profile companies, has raised the target speed to 480 Mbps, which
is 40 times faster than USB 1.1.
-
With the increased bandwidth, a broader
range of PC peripheral applications can take advantage of the benefits of
USB. These peripherals include high-end networking devices, digital video
cameras, next generation scanners, high-end printers, and fast storage
devices. In many cases, USB 2.0 can replace SCSI connections.
-
The USB 2.0 specification is expected for
final release by early year 2000. Leading chipset manufacturers, will have silicon by the second quarter of 2000. Leading
system and peripheral manufacturers are planning to introduce USB 2.0 products in
the last quarter of 2000. All USB 1.1 systems and peripherals are expected to
co-exist with those of the new USB 2.0.
