      i used to have an mp3-player with only an audio jack, and a USB-to-TRRS cable for charging and data transfer.

      i think it had 64MB of storage?

      point is, it’s been a thing

      Edit:

      also my keyboard! the two halves are connected together via audio jack.

        I saw that prison laptops in the US can’t have USB but can have an aux port and I’ve wondered since then if that couldn’t be cheesed.

          TIL. I mean, the headers on most boards are easy to find, so a few paperclips and some tape could be your USB port. And most built-in peripherals use the interface so it probably isn’t disabled. The rest depends on how thoroughly their IT vendor locked things down.
