awesome utility . I purchased a $50 usb cable inspector on Ali express because usb-c compatibility is atrocious. there are dozens of protocols, (data, multiple PD, EPR, various wire gauges, various pinouts connected etc).

USB c is really just a connector standard, but vendors sell the cables as if it’s a cable standard. It’s a failure of the USB standards group to establish conduductor, pinout, shielding and protocol standards for consumers to understand.

There should be color and markings on USB C cables similar to resistors so you can immediately tell WTF the cable is capable of before and during use.
