Abstract
A method for detecting a type of a port connected to a USB connector and a rechargeable device with a USB connector, a USB controller and a power management module. The power management module selectively powers up the USB controller depending on the type of port connected to the USB connector. A hardware detector is connected to the USB connector for determining the port type. If the port type is for recharging only then the power management module does not enable power to the USB controller.
