Abstract:
A USB interface controller chip comprises a pair of signal ports for being connecting with a pair of USB signals and a power node for being connecting with a supply voltage characterized in that the controller chip is built-in with a pull-up resistor connected between the power node and one of the pair of signal ports, and the pull-up resistor has a resistance consistent to USB standard but has a tolerance larger than that defined by USB specification.
