USB-A to USB-A cables do not exist

wtf are you talking about, of course they do.

[–] jet@hackertalks.com 8 points 11 months ago* (last edited 11 months ago) (1 children)

They meant cables in spec with the USB specification at the time usb-a was new.

Now with usb-c, it's kinda moot, as most cables are male to male anyway.. of course that means we're more likely to see USB-C female to female adopters now

[–] BorgDrone@lemmy.one 4 points 11 months ago

USB-C female to female adapters also are out of spec. The USB standard does not allow for extensions. USB cables only have male connectors (with the exception of USB-OTG dongles).

Show me where in the USB standards these are specified.

This is like saying that a building isn't a building if it's not up to code

[–] evidences@lemmy.world 6 points 11 months ago (1 children)

Or like saying usb-a to usb-c adapters don't exist because they're not part of the standard but we all have like six of those damn things even though we've never actually bought a single one.

[–] BorgDrone@lemmy.one 3 points 11 months ago (1 children)

But those are actually part of the standard.

[–] evidences@lemmy.world 1 points 11 months ago (1 children)

Are they? Everything I can find seems to say they aren't.

I remember when the first usb-c Macbooks hit stores Apple didn't have usb-a to c adapters for sale because they weren't in spec, a lot of reviews mentioned that.

You can find compliance requirements in the document linked here: https://www.usb.org/document-library/usb-type-c-connectors-and-cable-assemblies-compliance-document

You want to look at table 3-6 for requirements for USB-C to legacy USB adapters.

[–] theKalash@feddit.ch 14 points 11 months ago (1 children)

They cables and exist and they work. So being "specified" doesn't mean jack shit.

[–] BorgDrone@lemmy.one 0 points 11 months ago (1 children)

They might sometimes work. They aren’t guaranteed to work.
