Usb-C and its overengineered history By Tempo on Vrchat

Man i had that video saved to watch later so i had time to pay attention to it.

This was ridiculously entertaining and informative. I thought the naming scheme was a mess, it pales in comparison to the hardware complexities.

It seems fitting this was explained by an internet fox

I'd have considered it to be a Sci-fi if in 2010 someone told me that one day there will be a cable that can charge your laptop/phone or whatever else you want, as well as transfer a ton of data, including connecting to high resolution monitors.

It's a big achievement.

Yes, it's cool but I've run into one unfortunate problem with USB-C. Because the one available fast USB-C port on my tower-cased PC is in back, I got a 1M high-quality, high-bandwidth passive USB-C male to female extension cable so I could plug in my fast USB-C card reader without crawling under the table. Unfortunately, I learned to get max speeds (in this case 20gbps), it can "matter" which side of the USB-C cable connector faces up. In other words, if I don't get max speed, I need to turn one of the connections over (either from the card reader to the extension cable or the cable into the PC).

Apparently, this is a known issue and has to do with using the extension cable with a female USB-C on it instead of male on both ends. I always thought USB-C was "smart" and negotiated the connection so which side faced up didn't matter and, usually, it doesn't - but apparently not with a passive female connector in the chain. I guess I could get a cheap USB-C dock but most of those have permanently attached cables that are only 0.25M or 0.5M, not long enough for my use case. It seems odd that a short passive cable can't just extend the connector on the card reader electrically 1M and remain transparent to the negotiation from PC port to card reader connector.

I did look it up and confirmed it's not a shortcoming in the extension cable, card reader or PC port, it's just that "Yeah, USB-C can't handle that." In light of all the apparent over-engineering and USB-C's other amazing abilities, it's seems like an odd miss.

An extension cable with a USB-C plug on one end and a socket on the other is explicitly out of spec, to be clear. Also the socket-socket coupling, though I do have a handful of those for test purposes and extenuating circumstances.

Do you really need an extension cable? Officially USB-C extension cables shouldn't really exist, that's probably the biggest downside.

Do you really need an extension cable?

Well, I explained about my tiny portable USB-C SD Card Reader designed to plug directly into a laptop's USB-C port (hence no cable, male plug) and not wanting to crawl under my desk to reach the USB-C port on the back of my tower PC. Short of crawling under the desk, a 1M extension cable seems like the only reasonable solution.

Firewire/IEEE 1394 nearly had the potential to do the same, no pun intended, many years before USB-C.

Unfortunately it turned into a bit of a corporate punching bag, falling victim to both brand ego as well as higher supporting controller costs and licensing nonsense.

Ars Technica did a great little writeup on it a while back; well worth checking out, even for everyone who lived through the drama firsthand at the time:

Yeah apple uses ThreadX as firmware on some on their WiFi chips and cables yet it is the whole OS for some cheap feature phones and smartphones.

Oh yes regardless of all the issues it has going on, in most cases usb has provided a pretty decent universal cable.

Looks like china may be doing that for tv’s with GPMI. A challenge to hdmi with just massive power and data abilities that make me think one could power and drive a tv with one cable

Woah, opening a part of the internet unworldly to me. Their channel description:

We are a network of working professional furries interested in STEMM.

A free, VR, and what seems to be a serious, seminar with silly VR characters... you know what, fair lol. I won't argue with academia done in earnest (that said, I have no knowledge on this topic to account for it's credibility lmao).
