Abstract:
1. A Universal Serial Bus (USB) device for exchanging data with a USB host connected via a USB cable, the USB device comprising: a USB encoder for outputting USB encoding data: a reset controller for generating a reset control signal having a first state and a second state that is activated in a predetermined logic level when the USB device is to be reset, wherein the reset controller comprises: a data output unit for selecting and outputting one of the USB encoding data and a logic low signal, and a first output enable signal, in response to the reset control signal, wherein a second output enable signal controls a data path between the USB host and the USB device in response to the reset control signal, wherein when the reset control signal in the first state is applied to the data output unit, the data output unit outputs the first output enable signal as the second output enable signal to control the data path, and when the reset control signal in the second state is applied to the data output unit, the data output unit outputs the logic low signal as the second output enable signal to control the data path.
