USB was supposed to rule them all but it’s now a mess of standards sharing the same connector. Different speeds, voltage, charging protocols, alt modes, even the number of pins used is variable… For those asking, the thing is available on Kickstarter
Out of curiosity, is there a reason that this couldn’t be an Android app? I would think that there should be some way to check a cable’s functionality by plugging it into a phone and a computer.
It could be, but I imagine the reported capabilities would be limited by the connected devices. So if your phone doesn’t support USB SuperSpeed 80gbit/s, it wouldn’t be detected by the app.
