NEW ORLEANS -- Intel Desktop Products Group vice president Pat Gelsinger announced the release of the final USB 2.0 specification here today in his keynote address at the Windows Hardware Engineering Conference (WinHEC).
The high-bandwidth Universal Serial Bus 2.0 spec is the technical launch pad for consumer electronics products with more functionality, including higher-resolution videoconferencing cameras, next-generation scanners and printers, and faster broadband Internet connections. The technology was jointly developed by the USB 2.0 Promoter Group, consisting of Compaq, Hewlett-Packard, Intel, Lucent, Microsoft, NEC, and Philips Semiconductors.
USB 2.0 will extend the speed of the peripheral-to-PC connection from 12 Mbits/s on USB 1.1 to up to 480 Mbits/s -- 40 times more than current capabilities. The higher bandwidth will support such applications as digital image creation and web publishing, where multiple high-speed peripherals run simultaneously.
USB 2.0 was ramped in just a little over a year, Gelsinger noted. "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," he said. "Also, because USB 2.0 will be fully forward- and backward-compatible with current USB systems and peripherals, working with existing cables and connectors, consumers have the benefit of using devices they already have."
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 is also expected to lead to the development of higher-performance peripherals that will bring new applications to the PC, Gelsinger said.
