Abstract
A circuit and method of providing power to an external peripheral which employ a loopback circuit as an indicator to deliver power. The loopback circuit includes first circuit lines which are coupled together and which receive only a first signal from a port in the computer and route the first signal back to the port. The circuit further includes second circuit lines which carry second signals between the port and the peripheral device, and a third circuit line carries power to the peripheral device from the computer. The method includes the step of sending a signal from a port in a computer to a first circuit coupled to the port, receiving the signal by the port from the first circuit, and providing power from the computer to the peripheral device through a second circuit between the port and the peripheral device.
