Citation? The USB-C specification is the physical specification. All the other stuff is a USB specification but it has nothing to do with USB-C. https://www.usb.org/sites/default/files/usb_type-c_language_product_and_packaging_guidelines_final.pdf https://www.usb.org/sites/default/files/usb_type-c_language_... https://webstore.iec.ch/publication/25676 https://webstore.iec.ch/publication/25676 The layman confusion the USB-PD and USB-3.2 specifications is no different than someone thinking they can get 10gbe over a 1000m cat-5 cable because the ends plug into their 10Gbe adapter.

You're absolutely right, I stand corrected. But the author's complaint is still legitimate: in the context of billions of consumer devices, the diversity of behaviors is a problem. With RJ45, as long as the cable wasn't defective, it generally wouldn't fail completely. And relatively few consumers ever wired their own networks, whereas virtually everyone has to deal with USB-C-equipped devices.

  >With RJ45, as long as the cable wasn't defective, it generally wouldn't fail completely. That's just not true, and I don't mean this to be demeaning but you clearly haven't had to install new hardware into an old datacenter. I can't tell you how many times I've run into situations where a 1Gbe port would auto-negotiate to 10Mbps half-duplex. Did it technically not fail? I guess... but the line was so lossy you couldn't get a ping to complete much less an actual session of any sort.

    I can tell you that, as a consumer who has wired a lot of small office and home Ethernet, I've never seen a failure like that. On the other hand, I've seen lots of unexpected behavior with USB. I don't doubt your sincerity, but the reality is that very few consumers have to rebuild data centers. Lots of them need to power personal devices with shared USB cables and power supplies.
