USB 2 Spec From WinHEC...
USB 2.0 PROMOTER GROUP ANNOUNCES RELEASE OF FINAL SPEC
Intel VP Underscores Tremendous Progress in Development of Technology in WinHEC Keynote
WINDOWS HARDWARE ENGINEERING CONFERENCE, New Orleans, April 27, 2000 - New classes of high-performance PC peripherals are within reach with the release of the final Universal Serial Bus (USB) 2.0 specification. The technology is developed by the USB 2.0 Promoter Group, consisting of Compaq, Hewlett-Packard, Intel, Lucent, Microsoft, NEC and Philips Semiconductors.
As announced today by Intel Desktop Products Group vice president Pat Gelsinger in his keynote address here, the final spec of the high-bandwidth USB 2.0 is the technical launch pad for products with more functionality, including higher-resolution video conferencing cameras, next-generation scanners and printers, secondary storage and faster broadband Internet connections.
USB 2.0 will extend the speed of the peripheral to PC connection from 12 Mbps on USB 1.1 to up to 480 Mbps on USB 2.0 - or 40 times over existing capabilities. The higher bandwidth will support the most demanding PC user applications, such as digital image creation and web publishing, where multiple high-speed peripherals will be running simultaneously.
"The ability of the USB 2.0 Promoter Group to deliver the final spec in a little over a year after its formation is a testament to the solidarity of the seven member companies and the tremendous support of PC industry vendors in the development of this technology," Gelsinger said.
The rapid ramp of USB 2.0 can also be attributed to the evolutionary nature of the technology.
"Since the high-speed mode has the same basic
architecture of USB, migrating existing USB peripherals to USB 2.0 is a
much easier task than transferring to a brand new technology,"
Gelsinger said. "Also, because USB 2.0 will be fully forward and
backward compatible with current USB systems and peripherals, working with
existing cables and
The first USB 2.0-enabled systems and peripherals are expected in the marketplace in the fourth quarter of this year as part of the initial ramp. Broad deployment is anticipated in 2001.
USB 2.0 complements higher-performance PCs and user applications, enabling both to be more productive. Scanners, for example, can create a high-resolution digital image in seconds on USB 2.0, versus minutes on USB 1.1 The time to download a "roll" of digital photos also will be slashed from minutes to seconds. Consumers will also find that they can back up a gigabyte of data from their PC hard drive in less than a minute on USB 2.0, a task that took about a half-hour on USB 1.1.
USB 2.0 is also expected to lead to the development of higher performance peripherals that will bring new applications to the PC, Gelsinger said.
I/O connectivity is being further advanced with the IEEE 1394 standard. USB 2.0 and 1394 primarily differ in terms of application focus. The USB 2.0 Promoter group expects USB 2.0 to be the preferred connection for most PC peripherals, whereas IEEE 1394's primary target is audio/visual consumer electronic devices such as digital camcorders, digital VCRs, DVDs, and digital televisions. Both USB 2.0 and 1394 are expected to co-exist on many consumer systems in the future.
The momentum of the release of the final USB 2.0
spec will be sustained at the next major event for the technology: the USB
2.0 Developers Conference, May 15-18 in Anaheim, Calif. Information,
