The USB Implementers’ Forum (USB-IF) is a non-profit organization to promote and support the Universal Serial Bus. Its main activities are the promotion and marketing of USB, Wireless USB, USB On-The-Go, and the maintenance of the specifications, as well as a compliance program. It was formed in 1995 by the group of companies that developed USB. Notable members include Apple Inc., Hewlett-Packard, NEC, Microsoft, Intel, and Agere Systems. The working committees within USB-IF are: * Device Working Group * Compliance Committee * Marketing Committee * On-The-Go Working Group The USB-IF web caters for developers who can freely sign up to the developer web-forums and access documentation, however to join a working group one has to work for a member company or register as a member. The developer forums cover USB hardware and software development and is not an end-user forum. In 2014 they announced a new USB connection called "USB Type-C". It transfers data with 10 Gbit/s and charges devices with up to 100 Watts. The release is planned within 2014. ==Obtaining a vendor ID== A vendor ID is necessary for obtaining a certification of compliance from the USB-IF. The USB-IF is responsible for issuing USB vendor IDs to product manufacturers. The cost for issuing this number is US$5,000. Additionally, the use of a trademarked USB logo to identify certified devices requires license fee of US$3,500 for a 2-year term.〔(How to get a vendor ID from the USB-IF )〕 Some microcontroller manufacturers offer a free or low cost sublicense of their vendor ID for development/testing and limited production (generally under 10,000 units). Vendors offering this free service include: * Dream S.A.S.〔(Dream S.A.S. USB Vendor ID Application )〕 * Energy Micro〔( Energy Micro Application for USB PID Sublicense )〕 * FTDI〔(FTDI USB Vendor ID Application )〕 * Luminary Micro〔(Luminary Micro (now part of Texas Instruments) USB Vendor ID Application )〕 * Microchip〔(Microchip USB Vendor ID Application (dead link) )〕 * NXP 〔(NXP to offer global USB Vendor ID program )〕 * Silicon Labs〔(Silicon Labs USB Vendor ID Application )〕 * STMicroelectronics〔(STMicroelectronics USB Vendor ID Application )〕 * Texas Instruments〔(Texas Instruments USB Vendor ID Application )〕 Alternatively, many members of the open source community promote the use of USB VID 0xF055 (visually similar to FOSS) for open-source hardware projects. Although this VID is not registered to any company (as of October 2015), the USB-IF did not released any confirmation about reserving it for this particular purpose.〔(USB IMPLEMENTERS FORUM SAYS NO TO OPEN SOURCE )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USB Implementers Forum」の詳細全文を読む スポンサード リンク
