USB Implementers Forum

USB Implementers Forum, Inc. (USB-IF) is a nonprofit organization created to promote and maintain USB (Universal Serial Bus), a set of specifications and transmission procedures for a type of cable connection that has since become used widely for electronic equipment. Its main activities are currently the promotion and marketing of USB4, USB 3.2, USB Power Delivery, USB Type-C, and the maintenance of standards and specifications for the related devices, as well as a compliance program.

The USB-IF was initiated on 5 December 1995, by the group of companies that was developing USB, which was made available first during 1996. The founding companies of USB-IF were Compaq, Digital Equipment Corporation, IBM, Intel, Microsoft, NEC and Nortel. Notable current members include HP, NEC, Microsoft, Apple Inc., Intel, and Broadcom.

The working committees within USB-IF are:

  • Device Working Group
  • Compliance Committee
  • Marketing Committee

The USB-IF web caters to developers who may register freely for the developer web-forums and access documentation. To be part of a working group, however, a person has to work for a member company or register as a member. The developer forums regulate the development of the USB connector, of other USB hardware, and of USB software; they are not end-user forums.

In 2014, the USB-IF announced the availability of USB Type-C designs. USB-C connectors were introduced with transfer data with rates as much as 10 Gbit/s and provides as much as 100 watts of power.

In 2015, the seven-person board of directors, with Jeff Ravencraft as USB-IF president and chief operating officer, consisted of representatives of Apple Inc., HP Inc., Intel Corporation, Microsoft Corporation, Renesas Electronics, STMicroelectronics, and Texas Instruments.

In 2020, USB-IF announced updated USB Device Class Definition for MIDI Devices, Version 2.0, for MIDI 2.0 devices.
