ELECTRONIC DEVICE AND METHOD OF GENERATING VIRTUAL UNIVERSAL SERIAL BUS FLASH DEVICE

摘要

An electronic device connected to several USB devices. The electronic device divides a memory of each USB device to a plurality of memory blocks. Corresponding memory blocks of each USB device are combined to sectors. All the sectors form a virtual USB flash device. When data need to be written to the USB flash drive, the data is divided to data blocks according to a size of each memory block. The data blocks of the data are stored into the memory blocks of each sector. When the data need to be read from the virtual USB flash device, the data blocks of the data are read from the memory blocks of corresponding sectors. The electronic device combines the data blocks to integrated data.
