USB(universal serial bus)

Universal Serial Bus (USB) connects more than computers and peripherals. It has the power to connect you with a whole new world of PC experiences.
USB is your instant connection to the fun of digital photography or the limitless creative possibilities of digital imaging. You can use USB to connect with other people through the power of PC-telephony and video conferencing. Once you've tried USB, we think you'll grow quite attached to it!

Hi-Speed USB Development Tools

  1. If you want to 'upgrade' your PC to include Hi-Speed USB support, you can find PCI add-in cards at many retailers e.g. Fry’s, CompUSA, Microcenter, etc. All the add-in cards contained in the product search on this site have passed compliance testing and are certified to bear the USB logo.
  2. Hi-Speed USB Drivers are available for download using Windows Update. For additional information regarding Hi-Speed USB support in Windows XP and Windows 2000, please visit www.microsoft.com/hwdev/bus/USB/default.asp.
  3. Single Step Transaction Debugger (SSTD)
    This tool allows single transactions to be sent to a high-speed device. This is useful for low level debug. This application only works with the Windows 2000 and Windows XP driver for Hi-Speed USB (see item 2 above). The SSTD User Guide, which documents how to use the SSTD debugging tool, is included.
    Hi-Speed USB Information
  • Hi-Speed USB Press Releases - announcements from vendors developing Hi-Speed USB products.
  • USB 2.0 Adopters Agreement - The purpose of the Adopters Agreement is to facilitate the development of products that can interoperate, interconnect and/or communicate with one another in the manner defined in the USB 2.0 interface specification and its adopted supplements. Companies that sign an Adopters Agreement: (i) are obligated to license on a royalty-free and non-discriminatory basis, certain IP that would be necessarily infringed by products compliant with the final USB 2.0 interface specification or its adopted supplements; and (ii) will receive a license of the same scope from the USB 2.0 Promoters and other companies that have signed Adopters Agreements. This IP licensing obligation does not cover technologies your company may use to design or manufacture USB 2.0 products, which are not expressly set forth in the final USB 2.0 interface specification or its adopted supplements (e.g. manufacturing technology). You should carefully review the specific terms of the Adopters Agreement before signing. Any USB 2.0 Adopters Agreement shall only be effective if received within one (1) year after first sale of products that include 'Compliant Products'. See the USB 2.0 Adopters Agreement for details.

Wireless USB from the USB-IF

With more than 2 billion legacy wired USB connections in the world today, USB is the de facto standard in the personal computing industry. Soon, these same, fast, interoperable connections will become available in the wireless world, with the introduction of Wireless USB from the USB-IF.  Wireless USB is the new wireless extension to USB that combines the speed and security of wired technology with the ease-of-use of wireless technology. Wireless connectivity has enabled a mobile lifestyle filled with conveniences for mobile computing users. Wireless USB will support robust high-speed wireless connectivity by utilizing the common WiMedia MB-OFDM Ultra-wideband (UWB) radio platform as developed by the WiMedia Alliance.
UWB technology offers a solution for high bandwidth, low cost, low power consumption, and physical size requirements of next-generation consumer electronic devices.
  • Wireless USB is the first high-speed wireless personal interconnect technology to meet the needs of multimedia consumer electronics, PC peripherals, and mobile devices.
  • Wireless USB will preserve the functionality of wired USB while also unwiring the cable connection and providing enhanced support for streaming media CE devices and peripherals.
  • Wireless USB performance is targeted at 480Mbps at 3 meters and 110Mbps at 10 meters.
