In addition to turning ports on and off, the USBHub3+ can also independently enable and disable Voltage and Data:
Acroname's USBHub3c industrial USB Hub (plus the PD Logger add-on feature) can generate and capture arbitrary Vendor-Defined Messages (VDMs), enabling scalable automated testing, debugging, configuration, and deployment of USB-C devices.
We sometimes get questions about how to use the control port on our industrial USB Hubs. Each hub works a little differently:
USBHub2x4 is our compact two-host, four-port USB 2.0 hub.
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).
This guide is intended for users who need to:
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.
