Abstract: An operating system including a voltage converter, a processing circuit, and a protector is provided. The voltage converter converts an input voltage according to a feedback voltage to generate an output voltage. The processing circuit is coupled to the voltage converter and processes the output voltage according to a control signal to generate the feedback voltage. The protector is coupled to the voltage converter and the processing circuit and activates or deactivates the voltage converter according to the feedback voltage.

Abstract: An adaptive universal serial bus (USB) charging method and system are disclosed. In a low-power state, a USB device is charged with a non-USB charging mode. The non-USB charging mode is retained when no variation of a data signal coupled to the USB device is detected. When the data signal possesses variation for a first period, it is switched to a third proprietary charging mode.

Abstract: A hub device and corresponding method include a first chip having at least a first upstream port and a plurality of first downstream ports, a second chip, having at least a second upstream port and at least one second downstream port; and an external memory device, storing firmware data corresponding to the first chip and the second chip. One one of the first downstream ports of the first chip is coupled to the second upstream port of the second chip to form a tiered hub, and the first chip and the second chip are sequentially enabled and the first chip and the second chip sequentially load the corresponding firmware data.
