摘要： A method for expediting data access of a Universal Serial Bus (USB) storage device is disclosed. In a first embodiment, a data transmission procedure without the need of sending command block wrappers (CBW) is executed if a read command for reading data of a large memory space is received, and the addresses of the read commands are continuous. In a second embodiment, several write commands of continuous addresses are stored in a buffer area and combined into a larger single request command before sending to the USB storage device, so as to reduce the number of times of sending CBW and command status wrapper (CSW) required for the data transmission. In a third embodiment, more data are read and stored in a buffer area in advance when a read command is received, such that the next command can read data from the buffer area to improve the speed of reading data.
