Am I missing something? For practical use you only care if it carries a certain amount of packets per second without excessive retries, not whether it preserves the waveform exactly.

The $40 black-boxes do two things:
There is zero chance that a $40 black-box, even if it did a naïve packet pushing test, would deliver you reproducible results and introduces all sorts of other random variables."Excessive retries" sounds like exactly the sort of intermittent, hard-to-diagnose cable issues that you will not find unless you test the USB cable on a 6-figure rig. :)
