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.
The USBHub3+ can also independently enable and disable Voltage and Data:
We'll be working interactively using the Brainstem API in a Python console so you can see the results line-by-line.
Among other properties, using the USBHub3+ we can view:
Per-port Voltage
Per-port Current
Input Voltage
Input Current
Each port on USBHub3+ can operate in High Speed or Super Speed modes. There are three ways to view the speed of a connected port

If you are not familiar with PyInstaller it is an application that allows you to bundle a python file or project into a single executable by providing a fully encapsulated environment. The benefit being that you won't need to fuss with setting up a python environment. Simply execute the application.
Many times pyinstaller can be excuited without any additional commands such as:
From low to high-complexity applications, robots depend on robotic sensors for efficiency, safety, and performance.
At Acroname, we hate it when customers have issues with software and that’s why we provide deployments for Windows, Mac and Linux across various architectures.
The next-generation circuitry in today’s consumer and industrial electronics is smaller, faster, better. Consumers love the innovations. But test engineers are not as enthusiastic. Because that innovation comes with a striking downside: increased susceptibility to electrostatic discharge.
If the USB devices you’re using aren’t built for rugged environments, a catastrophic failure could — and probably will — happen. You’ll have to tell the C-Suite that all your electronic components fried because your ESD mitigations failed.
Often a simple USB switch with a physical button is used to switch USB devices between two different host computers. In many cases it would be nice to execute the host switch without physically pushing a button on the device. The Acroname Programmable USBHub2x4 hub allows a user to switch hosts programmatically without pushing a button.
The need for USB-C and power delivery ports in automobiles is speeding up, and the auto industry is adapting to the new demands. As the engineer in charge of testing, you’ll need to up your automated validation testing game.
