Cut Test Time, Eliminate Errors, and Scale Across Lines — No Cable Flipping Required

If you manage production lines for devices with USB-C ports, the real challenge isn’t the port — it’s the testing.

A single bad port means a return, a delay, or a hit to your metrics. And catching it after the fact? That’s expensive.

So your team tests manually — plugging things in, flipping cables, watching for signs of life.

But manual testing is slow.
It’s inconsistent.
It misses things.
And worst of all, it can’t keep up as you scale.

The Problem: Inconsistent Serial Port Assignment for multiple devices

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.
