Converting power over ethernet into a USB stream and separate power

Power over Ethernet (POE) can be converted into a USB stream and separate power. With these techniques, the benefits of POE can be obtained without requiring a terminal to be POE-enabled and without employing a terminal's Ethernet port. Many more terminals may therefore be powered via POE. A POE conversion device can include an Ethernet port by which the POE conversion device receives an incoming POE stream, a USB port, a power output, a power module and a USB conversion module. The power module is configured to extract power from an incoming POE stream to form an incoming Ethernet stream and provide the power to the power output. The USB conversion module is configured to convert the incoming Ethernet stream into an incoming USB stream with an Ethernet payload and then output the incoming USB stream with the Ethernet payload via the USB port.
