Loopback Tests Required for USB 3.1 Host and Hub Silicon Certification Mandate: Required Effective Date: January, 2016 USB 3.1 Host and Hub silicon certifications require loopback testing to be performed. Loopback testing is done through an honor system. Vendors are required to perform loopback testing prior to attending an authorized test lab or workshop. Loopback testing must be performed on the final configuration of the HW/FW of the device under test.

Questions Regarding Intel PIPE Specification Mandate: Informational Effective Date: October, 2009 The "PHY Interface for the PCI Express Architecture" (also known as the Intel PIPE Specification), is intellectual property of the Intel Corporation. It is strictly an Intel Corporation specification and the USB-IF does not distribute or provide support for it. Please contact admin@pciexpressdevnet.org for any PIPE related questions.

Blue Pantone (color) in USB 3.0 Connectors Mandate: Informational Effective Date: June, 2011 Section 5.3.1.3 of the USB 3.0 Specification defines Blue (Pantone 300C) as a recommended color for USB 3.0 A-connectors.
The use of blue pantone thermoplastics in USB 3.0 connectors is recommended on systems with a mix of USB 2.0 and USB 3.0 ports. For certification, the USB-IF does require that the user be able to clearly and easily distinguish between a USB 3.0 and a USB 2.0 port on a system; however, it is left to the system implementer on how to accomplish this. |

Support of SSC in USB 3.0 Products Mandate: Required Effective Date: July, 2012 All SuperSpeed USB products are required to properly support SSC. Satisfactorily passing all required SSC compliance tests is necessary in order to obtain SuperSpeed USB certification. All testing of the product must be performed with SSC enabled. Peripheral vendors MAY provide a utility to consumers that enables and disables SSC on the product. Whether to enable or disable SSC is to be the consumer's choice. |

USB 3.0 Certification Platform Mandate: Required Effective Date: March, 2014 Hosts, hubs and peripherals must be certified using Windows 8.1 (64-bit OS). USB-IF uses DELL XPS8700 ( 4th Generation Intel® Core? i7 Processor, 8 GB Memory ) and testing is performed using the on-board Intel host controller (Z87 Chipset). The latest Microsoft USB driver stack is used, and is updated by running Windows Update. The BIOS should be updated to the latest version, and can be downloaded from the Dell website ( Link for DELL XPS8700: http://www.dell.com/us/p/xps-8700/pd?oc=fdcwgp1312&model_id=xps-8700) . Please follow the PDK TechGuide document (TechGuide_xHCI_SSUSB_PDK_Ver1.9) for modifications to the DELL XPS8700 system. If you have further questions about the system configuration, email ssusbcompliance@usb.org. Please note the following testing requirements:
