USB in 1996: Let's make one connector that handles everything

USB in 2024: Let's make one connector do thirty different incompatible combinations of things

[–] [email protected] 11 points 6 months ago

To be fair, the goal is the same.

Not everyone needs the sheer CPU, power, and costs of a 40 GB/s connection.
Higher wattage chargers cost more
Not everyone needs a USB port that does video out (even if it should be standard now that virtually every new GPU should be compatible)
Even if the CPU and GPU support a feature, the OEM can use a cheaper controller
The controller firmware can lack support for a feature or be buggy

The USB forum can only solve points 4 and 5 without raising costs on the cheapest hardware.

All they had to do was require stamped icons on the ends of the plugs in the spec, and instead we have the current cable mystery clusterfuck 🤦

Why not label the ports and cables with:

10Gb/s
2.1Amps
1080p at 60hz

It's future proof and doesn't need a decoder manual other than basic literacy. It can be in whatever language the fucking keyboard is. If you want to be redundant but even more clear:

Universal Serial Bus -> (this hole right here)
Speed: 40Gb/s
Power: 2.4Amps
Audio/Video: 4K at 120Hz or 8K at 30Hz

Amps are not power

What about red USB-A ports, and USB-C ports with no symbol by them at all (like on phones and desktop PCs)?

I've literally never seen any of these except the top symbol.

The standard might be complicated if you want the specifics, but for everyday use it's incredibly simple, and I love it. The number of times I needed this information is 1, even though most of my devices, including an external monitor, are USB-C.
