Abstract
A method and system is provided for supplying power to a host via a USB port. The power is transmitted to the host using the standard VBUS and GND lines that are part of standard USB cables and connectors. The peripheral device includes a special USB descriptor block. During the standard enumeration process, the host reads this USB descriptor block and recognizes that the device can provide power to the host. A set feature command is used to start the power transmission to the host.
