Abstract
A USB power adapter has a built-in powerline communication interface and includes an electrical power connection to a powerline, such as a home power socket. The USB power adapter also includes one or more USB receptacles to connect to USB peripheral devices. The USB power adapter includes power converter circuitry and power delivery control logic for sourcing the USB power to the USB peripheral device connected to the USB power adapter, wherein the sourced USB power is compliant with the USB protocol. The USB power adapter includes a microcontroller unit (MCU) that interfaces with both the USB host controller and the powerline communication controller and has a protocol to establish the communication between the USB peripheral device and the powerline communication gateway server in order to create an IoT operation.
