@thomasfuchs I completely agree with your premise, but have you encountered random things that use an s-video or ps-2 style connector for power or communication in a seemingly arbitrary way? I have a few times and it’s always a surprise. Maybe there’s another standard for those connectors I’m not aware of?
@jesselamb @thomasfuchs I've seen worse – 12 V over USB-mini.
@jesselamb @thomasfuchs i have an NES style gamepad that uses a USB-A connector but isn't actually a USB device. a lot of NES clones do this, actually
