why isn’t it ok? why???
Meme “the number of people who think this is an abomination” over a photo of a USB-A to USB-A cable, “but think this is perfectly acceptable” over a photo of a USB-C to USB-C cable, “makes me sick.”
I’m not sure what the point is here. C is symmetrical and has absolutely no downsides, so yes, it’s objectively better.
I read the Wikipedia a little and apparently A to A cables can damage your devices, and the ones that do exist are for specific purposes and should only be used in those specific scenarios, and often they are more than just cables and have some computational stuff inside them
USB-A male to USB-A male is not in any USB standard (not entirely true, but compliant cables are very rare and don’t connect voltage), and if you plug it into a device it’s not meant for, the behavior is entirely unspecified. It will probably do nothing. But it might fry your USB controller that is not expecting to receive voltage.
USB-C to USB-C is in the spec, and if you plug in two host devices, they won’t hurt each other. You can actually charge a host device over USB-C, unlike USB-A.
That’s why it isn’t ok. It’s not the same thing, it’s not in the standard, and it can even be dangerous (to the device).
I think the argument that A-A should be in the spec.
But usb-c is just so much better all around.
It is a fact that USB-C is superior. Right off the bat, no more guessing if the end of the cable is facing correctly to be inserted into a port. My patience would quickly wear thin when I’d have to flip it around 3-4 times to finally insert it.
The joke is that A to A doesn’t make sense.
The joke is that USB-A shouldn’t be paired with another USB-A. It should be using a USB-B on the other end. USB-A to USB-A could potentially be damaging, as both devices will expect to be providing power. USB-B denotes that a device is “receiving” USB, not “sending” it.
USB-C is an absolute shit-show. Half a dozen types of identical looking cables all with different performance and compatability. They can be power only, USB-2 only, USB 3, 3.1, 5gb, 10gb. Some can carry 5A, others only 3A. Some may support thunderbolt. Cable sellers and manufacturers can/will claim anything.
For people selling USB-C devices it’s a massive support problem. It looks like the device is defective, but someone may just have swapped out the cable for their phone charger cable and there’s no way of telling.
Hm… I’ve honestly never experienced an issue with USC-C cables. I’m not saying they’re perfect but in my personal experience, I feel as they’re superior. Granted the USB-C cables I use are for my MacBooks and two of my mice.
USB-A requires three attempts to connect, C only one.
Six since it has A at both ends.
I actually found an A to A cable in my Big Box of Cables I Might Need One Day™ when trying to flash my Gotek floppy emulator with FlashFloppy firmware.
Huh, I’m not sure they are comparable.
Didn’t USB A and USB B use a master-slave relationship in which the male would (generally) always be the slave, whereas USB C uses agreement and discussion to decide the master and slave roles regardless of connector gender.
Please do correct me if I’m wrong. Also, do we say “agent” now instead of “slave”, or what is the new term?
I think the biggest problem I see with A to A is: who’s delivering power, and who’s receiving it? Maybe if you use it only with the device it came with then it’ll be fine, but if anyone tries to just hook up that cable to two random computers, it might actually cause a short circuit and fry something.
Whereas Type-C was explicitly made to handle such situations.
Or a shorter reason: Type-C cable is allowed by the spec while Type-A is not.
I believe the common terms now are “domme” and “sub”
actually they would be correct :
USB began as a protocol where one side (USB-A) takes the leading role and the other (USB-B) the following role . this was mandated by hardware with differently shaped plugs and ports . this made sense for the time as USB was ment to connect computers to peripherals .
however some devices don’t fit this binary that well : one might want to connect their phone to their computer to pull data off it , but they also might want to connect a keyboard to it , with the small form factor not allowing for both a USB-A and USB-B port. the solution was USB On-The-Go : USB Mini-A/B/AB and USB Micro-A/B/AB connectors have an additional pin which allows both modes of operations
with USB-C , aside from adding more pins and making the connector rotationally symmetric , a very similar yet differently named feature was included , since USB-C - USB-C connections were planed for
so yeah USB-A to USB-A connections are explicitly not allowed , for a similar reason as you only see CEE 7 (fine , or the objectively worse NEMA) plugs on both ends of a cable only in joke made cables . USB-C has additional hardware to support both sides using USB-C which USB-A , neither in the original or 3.0 revision , has .
With USB-C isn’t there still a slave-master dynamic that is now negotiated via software rather than hardware?
a slave-master dynamic
please don’t use that term, every time i see it i immediately verge on orgasming. you’ve already made me ruin 2 undergarments today. i have a serious bdsm kink and this is not funny.
I actually have several USB-A to USB-A cables.
Why?
For the glory of Satan, of course!
What if I put a C-to-A Adapter on both ends? Is that okay?
Yea but it’s inefficient. USB-A has a significantly lower transfer rate than USB-C so it’ll bottleneck
We peaked at USB mini B.
As it being disgusting or great?
Objectively disgusting. How can one connector be so chunky while still being asymmetric?
What’s a common thing that would require the use of USB A on both ends?
nothing worthwhile, as it’s not allowed (for a good reason)
