The Problem: Inconsistent Serial Port Assignment for multiple devicesA 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…

One of the challenges of USB PD is that devices need to work correctly with any PD sources or sinks they might encounter.  We frequently see shipped products that don't follow PD negotiations correctly.  Testing your USB-powered device against a single charger is not enough!  One of…

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…

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…

Multi-hosting on an Industrial USB HubIn modern manufacturing environments, devices often rely on local USB storage for configuration and firmware updates, data logging, and backup. It is often necessary to update or process this data by connecting the drives to another host, usually by manually…

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…
