Why aren’t motherboards mostly USB-C by now? (philip.greenspun.com)

Why aren’t motherboards mostly USB-C by now?::I’m beginning to think that the Windows PC that I built in 2015 is ready for retirement (though if Joe Biden can be president at 78, maybe this PC can last until 2029?). In looking at new des…

My Desktop does not have any USB-C ports, which kinda sucks sometimes as I'd need one for my phone. My server is an old HP desktop tower, with two USB-C ports, and I don't need it on there, as it's headless. My Laptop now has two ports, for charging and the docking station, and the ability to connect my phone.

Even if I had a USB-C port on my PC I would not move to USB-C for other accessories - keyboard, mouse, headphones etc. are all USB-A. My sticks are all USB-A, because they need to be compatible with every 2001 ThinkPad to install Arch btw. Only my encryption stick could be USB-C, but that would not have any advantages either.

The only accessory I would need as USB-C for phone compatibility, and therefore would need a USB-C motherboard for, would be a yubikey (or other 2FA sticks).

USB-C is very hard to manufacture and expensive as fuck as a result.

thats why.

Especially when most devices don't need the bandwidth or power needs of USB-C.

Source? Why is it expensive?

I know for a fact that USB-c is about 1.5× mirco-b.

Since USB A is not a slave connector that are no comparable boards on adafruit. So I asked Bing AI:

According to the web search results, the cost of a USB-C connector on a motherboard depends on various factors, such as the manufacturer, the chipset, the data standard, and the features of the motherboard. However, based on some examples of motherboards with USB-C ports, the price difference between USB-C and USB-A connectors with the same speed (USB 2.0) is not very significant. For instance, the ASRock B550M-ITX/ac motherboard has one USB-C port and four USB-A ports, all with USB 2.0 speed, and costs around $120. The [ASRock B450M-HDV R4.0] motherboard has six USB-A ports, all with USB 2.0 speed, and costs around $70. The difference in price between these two motherboards is $50, but this is not only due to the USB-C connector, but also to other factors such as the chipset, the memory slots, the audio codec, and so on. Therefore, it is hard to estimate the exact cost of a USB-C connector on a motherboard with USB 2.0 speed, but it is likely to be less than $10.
