Abstract

A method for providing USB power including the steps of running a POE cable from a power source to an adapter, the adapter having a POE connector for receiving electrical power from the power lines of the POE cable, a transformer circuit and a USB connector where the data lines of the POE cable terminate prior to the data lines reaching the USB connector and the power lines of the POE cable provide power to the USB powered device, adapting the POE power from the POE cable to USB power and making the USB power available to the USB connector.

Claims

1-13. -13. (canceled)

14. A method for providing USB power at a location remote from a power supply comprising the steps of:

a. running a POE cable having one or more power lines and one or more data lines from a power source to a power adapter, the power adapter comprising a POE connector for receiving electrical power from the power lines of the POE cable, a transformer circuit and a USB connector, and a termination point in the data lines of the POE cable prior to the data lines reaching the USB connector, leaving only the power lines of the POE cable to connect with and provide power to the USB powered device;

b. transforming the POE power from the POE cable to USB power; and

c. making the USB power available to the USB connector.

15. The method of claim 14 further comprising mounting an AC electrical box in the location remote from the power supply.

16. The method of claim 15 further comprising mounting the power adapter within the AC electrical box.

17. The method of claim 15 further comprising mounting a cover plate on the AC electrical box.

18. The method of claim 14 wherein one or more USB connectors are associated with a single POE cable.

19. The method of claim 16 wherein the POE connector is positioned to accept a POE cable internal to the AC electrical box and the USB connector is positioned to be accessed external to the AC electrical box.

20. The method of claim 14 wherein the POE connector is taken from the group consisting of an Ethernet receptacle, spring contacts, screw down contacts, push-in contacts and stripped wires.

21. The method of claim 20 wherein the POE connector is an Ethernet receptacle.

22. The method of claim 14 wherein the USB connector is taken from the group consisting of USB Type A, USB Type B, USB Mini-A, USB Mini-B, USB Micro-A, USB Micro-B, Apple dock connector, spring contacts, screw down contacts, push-in contacts and stripped wires.

23. The method of claim 22 wherein the USB connector is a USB Type A receptacle.

24. The method of claim 14 wherein one or more USB connectors are associated with a single POE power cable

25. The method of claim 14 wherein the power adapter is a self-contained device in a case.
