im fine with using any cable, be it 30 pin, lighting, usb c, etc. etc. As long as everyone uses the same cable. Keep it simple, convenient, and reduce extra waste.
But that’s not what we have with USB-C. Now, the situation is even more complicated than it was before. We still have a whole bunch of different cables, but now they all look the same and use the same connector. You can no longer easily tell them apart and there is no easy way to tell from the port on a device what features it supports and what cable it needs.
If I see a USB-C port on a device it tells me exactly nothing. Is it a USB host or not? Can the port be used to charge the device ? At what wattage? How big a charger do I need? What kind of USB data transfer speed does it support ? 12Mbit, 480Mbit, 10Gbit? Does the port support Thunderbolt? Displayport alt. mode? HDMI? Analog audio? MHL? HDMI? VirtualLink? What cable do I need ? a 5W, 10W, 30W? 60W? 100W?
A 40 Gbit 100W Thunderbolt 4 cable looks exactly the same as a 5W 480Mbit USB 2.0 cable. A cable that can carry a displayport signal looks exactly the same as one that can’t.
And shit is even more confusing than that. The USB-C spec supports an HDMI alt-mode. Cables with a USB-C connector on one side and a HDMI connector on the other exist. You’d think that to be able to use this cable your device needs to support HDMI alt. mode. Nope. HDMI alt. mode isn’t actually used, not even in USB-C to HDMI cables. Instead all such cables require DisplayPort alt. mode, as they all contain a displayport-to-HDMI converter chip.
So simple and convenient that we now have this USB-C standard.
