$300 Vision Pro developer strap is just an expensive USB2 device::Apple is selling developers a $300 USB-C dongle to connect the Apple Vision Pro to a Mac, but in this incarnation, it turns out to be no faster than Wi-Fi.

It's hilarious how Apple still insists on making all their mobile devices USB 2. Have they not cracked the code for USB 3 after 11 years?

USB 4 was designed 4 years ago ( https://en.m.wikipedia.org/wiki/USB4 ) and they still using usb 2? TIL

USB 2, 3 and 4 are not direct new versions depracating previous ones. Those are tiers, versions are reprecented after the point, like 3.1 is directly better than 3.0 .

USB 2 is not something that shouldn't be used because USB 3 exists. It is just simpler, just four pins, two for power and two for data, meanwhile USB 4 requires much more complex stuff. Just like new Intel i7 processor does not invalidate new Intel i3.

Still on a high-end phone 2.0 is bad, like putting i3 on high-end laptop.

What is bad, that is asking such prices for USB 2, that's what I've meant, it's like selling another 8gb of ram to upgrade to 16gb total for 500$

The pro models aren’t usb 2, just the normal models, as those are using the same processor as last gen. The usb controller is in the processor and last gen they were using lightning (which was usb 2.0).

The iPhone 15 pro is usb 3 and I believe current gen iPads are either usb 3 or thunderbolt

The iPhone 15 pro is usb 3

After the EU forced them to adopt USB C

[–] [email protected] 15 points 1 year ago (2 children)

It's not about USB C but about the USB version. Only their Pro models have USB 3 but the other ones have USB 2.

[–] tb_ 5 points 1 year ago* (last edited 1 year ago)

USB 3 wasn't an option whilst they were sticking with lightning, and if the EU hadn't forced them they clearly wouldn't have switched.

The reason the new non-pro iPhones use USB 2 is because they still use the old chip which previously used lightning, and as such never had a reason to support USB 3.

So I would say this is about the connector, even though you're technically correct that the protocol is separate from the standard.

The reason they have USB2 is because they are using the same motherboard as previous models. They just soldered the USB-c port to where their lightning port used to be.

Meaning their lightning port was about as fast as USB2.

Not the same motherboard, but the same SoC.

Yes only the very top model. But get this. They shipped it with a USB 2.0 only cable. You know, just to stick the knife in a little bit anyway. Those guys sure know how to make a joke.

[–] [email protected] 1 points 1 year ago

The very top model is the Pro Max. Pro is the second top model, by price. But yeah…

As a side note, the cable is actually really nice if usb 2 is fine. It’s super flexible and braided, all of my other braided cables are much more stiff. I would buy a longer one if they made one.
