The USB Implementers Forum (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 USB, Wireless USB, USB On-The-Go, and the maintenance of standards and specifications for the related devices, as well as a compliance program.
The USB-IF was initiated in 1995.
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
In 2014, the USB-IF announced the availability of USB-C designs. USB-C connectors can transfer data with rates as much as 10 Gbit/s and provides as much as 100 watts of power.[4]
In 2015, the seven-person
In 2020, USB-IF announced updated USB Device Class Definition for MIDI Devices, Version 2.0, for
Obtaining a vendor ID
A vendor identification is necessary for obtaining a certification of compliance from the USB-IF. The USB-IF is responsible for issuing USB vendor identification numbers to product manufacturers. The cost for issuing this number is US$6,000 per year. Additionally, the use of a trademarked USB logo to identify certified devices requires a license fee of US$3,500 for a 2-year term.[6] Some microcontroller manufacturers offer a free or low cost sublicense of their vendor ID for development/testing and limited production (generally less than 10,000 units). Vendors offering this free service include:
- Dream S.A.S.[7]
- Energy Micro[8]
- FTDI[9]
- Luminary Micro[10]
- Microchip[11]
- NXP[12]
- Silicon Labs[13]
- STMicroelectronics[14]
- Texas Instruments[15]
Alternatively, many members of the open source community promote the use of USB VID 0xF055 (which looks when written like "
