I recorded a cell phone vide where I used a USB cable tester to show their cable was wired 1-8, 2-7, 3-6, 4-5, 5-4, 6-3, 7-2, 8-1 instead of straight-through. I also showed another cable testing correctly.

I showed that when the SmartQ q7 tablet computer was plugged into my PC's USB port using the cable my PC threw a warning about excess power drain, but when another cable was used, it did not throw an error. I proved that by recording a cell phone video.

I might have also used a USB power meter but I do not remember.
