Usb Agreement

For a product developer, using USB requires a complex protocol and involves a „smart“ controller in the device. Developers of USB devices for public sale generally must receive a USB IDENTIFIANT that requires them to pay a fee to the USB implementation forum. Developers of products using USB specifications must sign an agreement with the Imlementers Forum. The use of USB logos on the product requires an annual fee and membership in the organization. [5] Some observers who have noticed Apple`s continued use of proprietary non-micro-USB charging ports on their smartphones felt that Apple was not in compliance with the 2009 joint EPS agreement. However, the European Commission confirmed that all MoU signatories have „fulfilled their obligations under the Protocol[6] and stated that „with regard to Apple`s past and current proprietary connectors and their compatibility with the agreement, the Protocol authorizes the use of an adapter without prescribing the terms of its provision“[15] and „The Commission has no evidence that Apple has breached the agreement.“ The iPhone 5 can be used with an adapter, so it can be connected to the common charger. [16] In order to develop and formalise the required technical standards, the Commission has given CEN, CENELEC and ETSI a standardisation mandate for a common „mobile phone charging option“. In response, CENELEC has set up a task force to develop the interoperability specifications for a shared external power supply. In accordance with the Dresden agreement signed in 1996 by CENELEC and the International Electrical Commission (IEC), the work was transferred to the CIS. The objective was the development of the IEC International standard, IEC 62684:2011. [3] The common EPS specification is highly based on existing electromechanical USB standards – in particular the USB battery charge specification. By the mid-2000s, many mobile phone manufacturers (as well as manufacturers of other small battery-powered devices) had begun designing their products with the ability to use the 5V power supply of a USB port to recharge batteries. The USB Implementers forum, which detects this trend, updated the USB standard in 2007 to better take into account this application for charging batteries from popular USB ports, including by defining „charging ports“ capable of providing more electricity, allowing faster charging of batteries. [7] [8] In November 2010, the CIS signed an agreement with the USB Implementation Forum that led the CIS standard to introduce USB specifications into the INTERNATIONAL CEI 62684:2011 standard.

The Open Terminal Platform Industry Forum (OMTP) clarified the requirements of GSMA`s universal charging solution and published these requirements in 2009 under the title „Common Charging and Local Data Connectivity.“ This document shows the three components of a common charging solution (CCS): a charging port and a local data connector (LDC) at the „terminal“ (for example. B a mobile phone), which consists of a micro-B or an AB micro-tank; A common power adapter (CPS) with a Type A socket; and a removable Micro-B Type A cable to connect power to the mobile phone. [34] In early 2011, 10 other service providers and another mobile phone manufacturer joined the agreement. [35] In December 2014, USB-IF has transmitted USB-IF USB 3.1, USB Power Delivery 2.0 and USB-C specifications to the CIS (TC 100 – audio, video and multimedia systems and devices) to be included in the international CEI 62680 (Universal Universal Bus Systems Data and Data Interfaces) standard, which is currently based on USB 2.0. [24] Media Transfer Protocol (MTP) was developed by Microsoft to give access to a device`s file system at a higher level than USB mass memory, not at file level, nor on hard drive blocks.
