I have a USB-C cable that has absolutely no markings on it. I don't know where it came from, so I don't know what kind of cable it is. I think it's a Thunderbolt 3 cable, but I'm not sure. It doesn't have the characteristic lightning bolt icon on it.
Given that I have several Thunderbolt 3 devices, is there any way I could test the capabilities of this cable using those devices? I have two Thunderbolt 3 hubs (one of which is a CalDigit TS3 Plus) and an external display, which when connected presents as three USB devices on a USB 2 hub, and a 1080p DisplayPort monitor.
Perhaps I could try to transmit as much data along the cable as possible and see where it tops off, but I'm not sure how to do that. Of course I'm open to other, possibly better ideas too.
