Abstract
A data duplication method and system used between USB devices is exploited to control data transmission between a source USB device and at least a target USB device without any assistance from a computer. The duplication system comprises at least a serial interface engine circuit, a CPU, and a data buffer unit. The CPU is connected to the source USB device and these target USB devices via these serial interface engine circuits. The CPU controls these serial interface engine circuits to transmit digital data in the source USB device to these target USB devices. The data buffer unit is connected to these serial interface engine circuits and the CPU, and is used to provide memory buffer space required during the digital data duplication process.
