For even a tech savvy consumer, USB Type C is a minefield. Trying to put everything into a single universal connector was a noble goal, but I fear the market has been confused by it all.
That's an understatement. The idea was great, but it forgot about one simple truth: keyed connectors to ensure compatibility (or rather, to block incompatibility) is a good thing. The mess this has resulted in is kind of epic in its insanity.
As for some technical things:
I don't even think USB signaling is mandatory in a USB-C connector, insofar as Thunderbolt devices don't support being connected to a computer via USB.
But Thunderbolt is, in a sense, a special case, in that other than sharing the connector, it's really a totally unrelated standard, in that both ports must support it, AND a Thunderbolt cable must be used (and a Thunderbolt cable cannot be used for USB.)
What's insanely confusing to people is that USB-C
isn't a numbered version of USB, but rather what I'd call a sister standard.
Ignoring the mini and micro variants (and the added-pin variants for USB 3.0), USB essentially has 3 kinds of connectors:
Type-A (used on the host end only)
Type-B (used on the device end only)
Type-C (host or device)
In theory, any two of these can be combined into one cable, though only USB-C can be on both ends of the
same cable.
And then we've got the numbered USB versions, which cover the speeds and features:
USB 1.1
USB 2.0
USB 3.0USB 3.1USB 3.2
Oh but wait, each version can have multiple speeds within it. Here's the bitrate, original connector types, and "marketing name" for the speed:
USB 1.1:
1.5Mbps, A/B: Low Speed
12Mbps, A/B: Full Speed
USB 2.0
1.5Mbps, A/B: Low Speed*
12Mbps, A/B: Full Speed*
480Mbps, A/B: High Speed
*these two modes are simply the USB 1.1 modes. So yes, manufacturers could, and often did, brand their 12Mbps devices as "USB 2.0" even though it's actually unchanged from USB 1.1.
USB 3.0
5Gbps (full-duplex), A/B: SuperSpeed USB
USB 3.1
5Gbps (full-duplex), A/B/C: SuperSpeed USB
USB 3.1 Gen 2
5Gbps (full-duplex), A/B/C: SuperSpeed USB
10Gbps (full-duplex), A/B/C: SuperSpeed USB 10Gbps
USB 3.2
5Gbps (full-duplex), A/B/C: SuperSpeed USB
10Gbps (full-duplex, single-lane), A/B/C: SuperSpeed USB 10Gbps
10Gbps (full-duplex, dual-lane), C: SuperSpeed USB 10Gbps
20Gbps (full-duplex), C: SuperSpeed USB 20Gbps
Oh but wait, didja notice how above I said "original connector types"? Yep, that's because USB-C also supports older USB standards. Perfect example is how many mobile phones use USB-C, but with only USB 2.0 (High Speed).
And then as you said, Power Delivery is overlaid on top of all that, with various combinations of device, charger, and cable producing different charging results.
Other than for Thunderbolt, I expect that premium cable manufacturers will start marketing "universal" USB-C cables that have all pins wired, and have thick power lines and are correctly configured for full-power Power Delivery.
What devices do you use where you've broken the USB-C connectors? This is honestly something I haven't been hearing much of, leading me to think that it's substantially more robust than earlier mini/micro-USB connectors. And (be honest with me, it's just curiosity, not judgment) are you someone who tends to be easy or rough on your equipment?
