Ensure your USB devices are market-ready, meet global regulatory standards and perform reliably.
Partner with Resillion as we are an USB-IF authorized independent test Lab (ITL) for USB device testing and certification. Whether you’re developing a USB peripheral, embedded host, or full system, our expert engineers provide comprehensive testing.
With the EU mandating USB Type-C® ports on all portable battery powered devices today, and laptops by 2026, manufacturers must ensure their products are compliant, interoperable and future-proof. Many other countries are following the EU by requiring or recommending USB Type-C®.
Our testing services help you:
Interoperability testing ensures your USB product performs reliably across a wide range of third-party devices, operating systems and usage scenarios. It’s not just about passing a spec, it’s about confirming your device behaves predictably in the field.
Your product is tested against a curated matrix of over 300 USB source, sink, and data devices. This includes a mix of certified and non-certified hosts, hubs and peripherals across multiple generations of USB standards (USB4, USB3.2, USB2.0 and USB PD).
We validate USB enumeration, driver loading, and power negotiation across Windows, macOS, Linux and Android environments.
We assess how different USB cable types (passive, active, EPR-rated) affect charging current, data throughput and signal integrity.
Charging performance is evaluated across multiple profiles:
If your device supports DisplayPort, HDMI, or Thunderbolt over USB-C, we test negotiation, signal switching, and display output stability.
We simulate real-world conditions such as:
Devices are tested using a modular testbed that includes programmable power supplies, USB protocol analysers, and automated switching matrices.
Each test case is executed under controlled conditions, with logs captured for voltage/current behaviour, enumeration timing and error states.
For products with unique use cases (e.g. automotive infotainment, industrial hubs), we offer tailored interoperability campaigns using customer-supplied or specially procured devices.
Ensure your product meets both technical and regulatory expectations for USB-C® performance, safety, and interoperability. To prepare your products for compliance, speak to an expert.
The EU’s EU External Power Supply (EPS) Ecodesign legislation and Common Charger Directive mandates USB Type-C® and USB Power Delivery (PD) for power above 15W on a wide range of consumer electronics and external power supplies. To help manufacturers meet these requirements, the USB Implementers Forum (USB-IF) has introduced the EU conformity programme, a streamlined path to demonstrate compliance with both USB specifications (IEC 62680) and EU regulations.
Resillion is here to help you meet those requirements efficiently and confidently.
The USB-IF EU conformity programme validates your product against the minimum mandatory requirements referenced in the EU legislation for:
USB Type-C® and USB PD specifications (IEC 62680 series)
USB 2.0, USB 3.2 and USB4® electrical and protocol compliance
USB battery charging 1.2 and source power test specifications
Functional and interoperability test suites (USB3CV, USB4CV, xHCI CV)
This is a subset of the USB-IF certification programmes for USB-C® and USB Power Delivery, which Resillion also provides.
