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?
You guessed wrong.

It's a ridiculously expensive and "home made" looking, but it saved my hands from OCD.
Ooh, I did guess wrong! That is an interesting specimen.
My suspicion is that they are experts in ergonomics, not in electrical engineering, so they probably aren't aware of how silly and possibly dangerous what they did is. Or perhaps they simply don't care because "it gets the job done", standards and specifications be damned.
Anyway, in this case I'm happy to be proven wrong. Thanks.
I known they outsourced the firmware development, so who knows, maybe the electronics hardware too.
