Fix Inconsistent Serial Port Assignments with USBHub3+

The Problem: Inconsistent Serial Port Assignment for multiple devices

A recurring issue when working with multiple USB-to-serial connections is that the operating system does not consistently assign port names. This is especially painful for end-of-line (EOL) functional test customers who are connecting multiple Devices Under Test (DUTs) at once, since it is important to know which DUT is passing or failing. 

USB-C-Switch for DisplayPort Alt Mode functional test

USB-C ports have to handle a variety of functions including data transfer, power delivery, and DisplayPort (DP) Alt Mode video output.  Device manufacturers need to perform factory End-of-Line (EOL) testing to make sure that their products meet specifications  In this blog post, we'll be looking at how to automate and speed up EOL testing of DisplayPort (DP) Alt Mode with Acroname's USB-C-Switch

Case Study: End-Of-Line Test and Provisioning

Introduction

This case study presents how an automotive supplier was able to automate firmware and OS provisioning and End-of-Line (EOL) functional final assembly testing using Acroname industrial USB hubs and switches and their USB Host switching features.  This automation resulted in reduced cycle times, less manual intervention and fewer errors while supporting a mix of software versions on the same production line.

USB Port Switching for Batch In-Circuit Programming and Testing

Enhancing Production Efficiency with Batch ICP

In device manufacturing, firmware is flashed onto devices using in-circuit programmers (ICPs).  automated batch programming can help remove the ICP bottleneck.  In this application note, we'll look at how to use USB port switching with Acroname's Industrial USB hubs to boost throughput for batch in-circuit programming and testing.

USB PD Sink testing with USBHub3c

I. Introduction to USB Power Delivery (PD) Sink Testing

USB Power Delivery (USB PD) is a convenient way to power a variety of devices.  Since a USB PD sink device could be connected to any PD source, sinks need to work safely and correctly with any source they might encounter.

The USBHub3c by Acroname is an industrial USB-C hub that can emulate any PD source up to 100 W per port to test PD sink capabilities.
