If you must have a USB (for whatever reason)

And you own a multiple Bimmer's stop being cheap

On a side note, don't devalue the benefit of having a USB port with condescension. Most peripherals use them, they are incredibly handy for in-person situations, and it's not like it is some kind of wild and crazy request.

I'd say USB is the most common of all computer ports.
