Disabling USB Port for Acroname Hub   Many customers have found the Acroname USBHub2x4 useful in production environments, but in some cases, when the hub is powered up/booted it may be best if the downstream ports are NOT enabled. This is particularly useful for cases when there…

In this week's video, we show an example of testing LEDs in a board-level functional test system. We used a simple circuit board we created for testing a new light pipe design as an example. The video shows just how easily MTM can be used as an engineering tool and manufacturing test…

Two example projects for USBHub2x4 With National Instruments We've recently been getting questions regarding the use of the Acroname USBHub2x4 from within National Instruments TestStand test management software. So we put together two example projects which wraps the BrainStem2 library…

INTRODUCTION TO MTMAcroname, Inc. has been bringing robotics and automation systems into the hands of engineers for more than 20 years. Our customers include some of the largest corporations and research institutions in the world all the way down to elementary school students. We also advise and…

Check out our new YouTube video "Up and running with BrainStem using our Python API". This video details how to properly configure your system to communicate with our Brainstem modules.  It includes: installing Python, pip, and the BrainStem API (.whl).  Once…

Not only do we make Manufacturing Test Modules (MTM), we also use them to test our own products. Using BrainStem® MTM modules to make a functional board level test system is incredibly simple. For the USBHub2x4, MTM allows us to make a test system that requires no external test equipment…

Using BrainStem Python for Turning USB Device On And Off Simple task automation for repetitive actions can be powerful aids in product development. Automatically connecting and disconnect devices from a USB bus is commonly done in manufacturing test and software regression test systems.…

Controlling data and power lines independently with HubTool applicationNotice that when the power line is enabled, the Android device indicates it as "charged". After enabling the data lines, the device then indicates that it enumerates as a media device from the USB Hub. Doing…

Setting up product manufacturing involves many complicated systems and processes. In order to produce millions of devices a month, companies need to massively scale these systems. Yet this scale is in direct conflict with fast product changes and time-to-market for "the next big thing". Major…
