The internal storage has nothing to do with USB. The USB port can enable a computer to see what's on the phone's storage. But there's nothing you can do about that, except damage the USB connector so that the USB data pins (there are 2 ins for power and 2 for data) don't work. But that eliminates a lot of other things, like connecting a flash drive to the phone, flashing firmware to it if you ever have to, etc.
