USB-C hubs are not permitted by the spec.

I just bought new PC, I spend almost 300 EUR on Motherboard alone, just so I had 2 USB-c (one back one front) and 2 nvme slots. Does that mean I'll only ever be able to hook up 2 devices to my PC ? If that's the case this sucks. I just cheeked there seems to be lack of usbc pci cards, and the ones that exist only have single ports :(

Here's a 4-port card: https://amzn.to/2WuAt4x

I have no idea why the standard isn't mandating clear markings (eg something like the bands on resistors, or whatever that works for color blind folks too).

Because nobody would follow them anyway. Apple wants white cables, some people want red, blue or yellow cables, so on. And the connectors are so small there is no place to put anything on them.

That's not true. It'd help a lot. Apple can use their cable and simply not say that it's USB3/TypeC/FancyX. No one would care if it would actually work.

But at least there were clear markings for those who care.

It would take up about 2 cm on each end of the cable, a set of bands, like a barcode. It doesn't even have to be that strikingly different in color.

I'm pretty sure the USB Implementers Forum is controlled by interests that think they benefit from things being confusing. At least, I can't think of any other explanation for allowing 1.5Mbit/sec and 12Mbit/sec devices to call themselves 'USB 2.0'

There was a comment about that here on HN a few months back and that kind of convinced me that it's to enable the very-very cheap gadgets to be at least compliant. Cheap chips, slow clocks, but at least they follow the protocol. At least that's the theory.

Sure you I wish that the state is in whatever it is that I prefer but thats unrealistic. As developer you have to be ready with whatever state you are in. Sure, If there are only small number of browser or all of my user is not disabled, I would prefer that and my job will be easier but that is not realistic. I have to be ready with whatever situation I've been dealt with. As developer my job is to solve problem and…

I can sympathize with wanting to solve as many problems as possible and as well as possible and to provide a great user experience; however, our ability as devs is necessarily limited and that should be accounted for. Both the developer and the user are in this together.

Good thing that developer/engineer are specifically trained for problem solving and managing complexity.
