发明名称 Control device for a USB interface and control method thereof
摘要 A control device for a USB interface including at least one first terminal for inputting the data to be transmitted and at least one second terminal for the transmission of the packet data on a bus; the packet data include one end-of-packet signal. The USB interface includes one circuit for the data transmission on said at least one second terminal; the USB interface is adapted to receive as an input a signal for the activation of the transmission circuit when data are received from the at least one first terminal and the transmission circuit includes a bias circuit. The control device includes a circuit for the detection of an end-of packet signal on said bus and a control circuit adapted to activate the bias circuit of the transmission circuit if said end-of-packet signal is detected by said detection circuit.
