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 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’ve actually used this to my advantage. I bought some cheap speaker/light combos which basically made the lights dance to the music. The only power connector was a wire that comes straight out of the device and into an outlet. But it did have a USB port for loading music from a USB stick. So naturally I plugged one side of a USB A into the port and the other side into a power bank and it just straight up worked.

      Hrm. I have a keyboard that requires an A to A cable and I think it works with the cable any way around…

      Might be wrong.

        It makes sense, if I remember correctly the older USB cable (i.e. everything before Type-C) are passive, so as long as the pins are wired symmetrically it wouldn’t matter which side is which. But whoever made your keyboard really blundered, there is no reason in the world why anyone would do this. There’s so many options: the B connector, mini USB, micro USB. All would make sense to put in the keyboard. A just doesn’t.

        Let me guess: you got it from an ultra cheap online store? AliExpress/Wish/Temu?
