● USB Type-C/PD Interoperability
MacBook Pro 16-inch Apple M4 Max chip (36GB Memory – 1TB SSD – 140W USB-C Power Adapter) or MacBook Pro 16-inch M4 Pro chip (24GB Memory – 512 TB SSD – 140W USB-C Power Adapter)
Models support both USB4 80Gbps and 140W of EPR power
Required for USB4 Interoperability testing as soon as possible
Required for USB Type-C/PD Interoperability testing by USB-IF Compliance Workshop #138
MacBook Air M1 (Apple M1, 16GB RAM, 256GB Storage) still required for both USB4 and USB Type-C Interoperability testing
● USB Certification Platform
Hosts, hubs and peripherals must be certified using Windows 11 (64-bit OS). USB-IF testing must be done on:
Dell XPS 8950 12th Gen and Dell XPS 8940 11th Gen are viable alternatives – however email TechAdmin to confirm
USB4 Compliance Program
USB4 DisplayPort Tunneling Link Layer
Only 1 DP Tester required (Teledyne LeCroy Quantum Data M42DE or Unigraf UCD 500 Gen2)
● RFI Testing
Required for Gen 1 (5Gbps) and up capable End-Product USB Type-C hosts and peripherals
Applicability table in specification incorrect
Applicability currently under USB-IF internal discussion, peripherals may change to hubs
Only required for USB Type-C receptacle products
USB Type-C/ Power Delivery
● EU Removes References to IEC 62680 (USB) Specifications
Reverts to USB specification naming schema
The EU will no longer refer to the IEC standards naming in their new regulations and they are in the process of changing the references back to the original USB-IF specifications naming
The USB-IF will be updating its IEC Conformity Program naming to align with the EU updated references/naming
This also entails updating USB-IF’s conformity and certification notices to ensure they are consistent with the updated naming
Final naming will be USB-IF EU Conformity to USB Specifications (full name) and EU Conformity (website sub-heading)
The USB-IF plans to Implement EU Conformity QbS program in Q2’25
● SPR and EPR Adjustable Voltage Supply (AVS)
USB PD CTS test equipment currently test SPR and EPR AVS capabilities
Test steps have been updated in newest USB PD CTS release
Will require additional testing using the QuadraMAX 2 test equipment in the future
Will use more precise voltage steps and test multiple ports at once
● USB Power Delivery Version Control
USB PD 3.2 v1.1 Silicon certifications eligible
USB PD 3.1 v1.8 to USB PD 3.2 v1.1 End-Product certifications eligible
Additional extension of grace period waivers may be approved by USB-IF Compliance Review Board
Vendors should email product details and extension timeline to techadmin@usb.org
