Abstract
A method is provided for detecting the data transmission rate of a USB controller by using a USB device having at least one program storage device. An IRQ signal of a timer is activated through a program. If the USB controller transmits a signal corresponding to a high-speed USB controller within a pre-determined period of time, the data transmission rate is set to a high-speed mode. If the signal is not detected, data transmission is set to a full-speed mode.
