ABSTRACT:
The present invention relates to an application of the Universal Serial Bus (USB) technology, and more particularly, to a USB apparatus with data storage and security token and control method therein. In an embodiment of the present invention, both mass storage and security token are implemented in a USB apparatus with a single controller. Thus, the host needs to enumerate the apparatus only once, and then may operate differentially in response to different commands. The mass storage is capable of swapping a mass of data, and has a file allocation table compatible with the system. The security token can be used for authenticating a person through digital certificates or biometric characteristics, maintaining the security of the computer and network applications.
