I'd think that if you had physical access to the USB port, you would also have physical access to the cash itself and could just take it.
I think that that would be a poor design. One box for the hardware (you don't need armoured car knuckle draggers messing with the electronics), and one box containing the cash (You don't need the maintenance nerds walking away with pocketsfuls of crisp new bills). Both of those would be inside a box that locks out the general public. Actually, I'd probably put the cash inside a box inside the cash portion of the machine, so the armoured car folks are not dealing with cash, but with locked boxes that they cannot open. They pull out the empty box, and load in the full one, much like replacing a toner cartridge. Actually, the electronics should be done the same way: a one piece, factory sealed, replaceable module.
