In addition to turning ports on and off, the USBHub3+ can also independently enable and disable Voltage and Data:
USBHub3c, combined with the External Load Feature, allows easy load testing and battery discharge of a variety of USB devices, including legacy Lightning, USB-OTG and USB-C ports, with and without USB Power Delivery (PD).

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.
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!
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.
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.
In 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 unplugging the drives.
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 Power Delivery (USB PD) sources need to support a broad range of power modes and sink devices. Be sure that your source can reliably handle any sink it might encounter.
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.
