PURPOSE: A multifunctional Bluetooth transceiving device having a USB interface function is provided to support a Bluetooth function in a PC in connection with the PC, and to store data received through a wireless communication system with data transmitted through a USB bus, thereby realizing Bluetooth USB adapter, USB storage, and Bluetooth storage functions in the single device. CONSTITUTION: A USB Bluetooth interface(45) is activated by an operation controller(41), transmits descriptor information to a PC, processes data of a USB serial interface engine(44), and transmits the processed data to a Bluetooth baseband processor(50). The Bluetooth baseband processor(50) processes the data in RF transmission-capable state, outputs the processed data to an RF transceiver(53), stores data inputted from a USB storage device interface(47), and stores data received through the RF transceiver(53). The RF transceiver(53) delivers the data transmitted from the baseband processor(50), codes a received RF signal, and transmits the coded RF signal. The operation controller(41) turns on the first switch(42), and activates the Bluetooth interface(45) and the processor(50).
