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.
From low to high-complexity applications, robots depend on robotic sensors for efficiency, safety, and performance.
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.
The problem USB devices often need to be disconnected and reconnected (plug-cycled) or reset. The reasons for plug-cycling a USB device are as varied as types of USB devices themselves. In service, the simplest solution to many USB-related problems is to reset the errant host machine or USB device.
