Abstract:
1. A multi-layer USB drive for storing data in a memory comprising: a. at least two printed circuit board assemblies, each one comprising:  wherein the circuit board assemblies are operatively connected to one another in a serial manner for exchange of data between adjacent assemblies upon access by a user and wherein at least one of the control microprocessors is security enabled requiring a user defined security input for accessing the memory of the printed circuit board assembly of that security enabled control microprocessor; b. a USB connector for connecting to a USB slot of a device, the USB connector operatively connected to only one of the printed circuit board assemblies; c. a USB hub on at least one of the assemblies for expanding the USB connection of the USB connector into multiple USB connections for the circuit board assemblies and for providing connection information to the control microprocessors of the assemblies; and d. an opaque housing completely enclosing the circuit board assemblies preventing at least the printed circuit board assembly or assemblies other than the one connected to the USB connector from being viewed.
