FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities,
IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication,
use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). IEC
takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the
date of publication of this document, IEC had not received notice of (a) patent(s), which may be required to implement this
document. However, implementers are cautioned that this may not represent the latest information, which may be obtained
from the patent database available at https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such
patent rights.
IEC 62680-1-2 has been prepared by technical area 18: Multimedia home systems and applications for
end-user networks, of IEC technical committee 100: Audio, video and multimedia systems and
equipment. It is an International Standard.
The text of this standard was prepared by the USB Implementers Forum (USB-IF). The structure and
editorial rules used in this publication reflect the practice of the organization which submitted it.
