In an exemplary embodiment, a system comprises a source, a power adapter, a USB port controller, a USB plug and cable, and a device. In one example, the device includes a rechargeable battery. After connecting the device to the USB port controller via the USB plug and cable, a reconfigurable module within the USB port controller sets a power mode by: (1) configuring an impedance network to present impedance modes that indicate available power modes, (2) detecting voltages on one or more of the USB conductors in response to each impedance mode, and (3) comparing the detected voltages to reference voltage levels to set one of multiple power modes. The reconfigurable module then controls the power adapter to transfer power according to the determined power mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive USB port controller","description":"An adaptive USB port controller is disclosed.
