Modifications to the USB specification have been made via [[Engineering change order|engineering change notices]] (ECNs). The most important of these ECNs are included into the USB&nbsp;2.0 specification package available from USB.org:<ref>{{cite web |url= http://www.usb.org/developers/docs/usb20_docs/ |title= USB 2.0 Specification |publisher= USB Implementers Forum |url-status=dead |archive-url= https://web.archive.org/web/20171203144114/http://www.usb.org/developers/docs/usb20_docs/ |archive-date= 3 December 2017 |access-date=28 April 2019 }}</ref>
