Usb C cable 100W rating.

[Mike Watterson]

Aha! So to sum up: USB C is a horse designed by a committee on mind altering drugs.

Glad we've cleared that up.

It explains a lot.

USB C (or "USB A", "USB B" etc.) is a connector specification, not a protocol.

Broadly true.
But there are USB 3.x and not USB 3.x compatible USB-A, USB-B and micro USB versions.

The connector specifications are dimensions, number of pins etc.

USB 1.x, 2.x and 3.x cover signalling, power and speed and don't need USB-C connectors.

Many gadgets simply have a USB-C connector replacing the older micro-USB with no extra functionality.

Plenty of things with USB-C connectors do USB 2.x max and no USB 3.x at all.

There are the areas on USB-C of power (might be regular USB 2.x, USB 3.x, PD or Qualcomm (and that has 3 revisions). Also use of USB -C for analogue audio, or digital video, neither of which is either really USB 3.x nor really a connector specification.

USB 3.2 Gen 2x2 is the latest signalling specification (20Gb/s), however the most common current fast specification in use is USB 3.2 Gen 2 (aka "Gen 1x2) which runs at a max speed of 10Gb/s.

It's not that common on any random USB3.x kit. Also "max" is a bit weaselily, as ever with every version of USB.

Just to confuse the matter further, there's also USB 3.2 Gen 2x1, previously known as USB 3.1 Gen 2, which also runs at 10GB/s but uses a different signalling protocol.

No surprise.
