A universal serial bus (USB) device is comprised of a receiver for receiving signals from a USB host through data lines, and a pull-up resistor circuit connecting pull-up resistors to data lines in response to control signals. The pull-up resistor circuit selectively connects a plurality of pull-up resistors with a data line in response to control signals. The pull-up resistor circuit controls a number of the plurality of pull-up resistors connected with the data line to cause a voltage level of the signal to be lower than a threshold voltage when the USB host resets the USB device.
