ABSTRACT:
The dynamic VBUS power source provides a system and method for dynamically powering USB devices. Briefly described, one embodiment is a method comprising determining when the USB device is a master device or a slave device, powering the USB device over a USB connector using a power unit when the USB device is the slave device, and powering a second USB device over the USB connector using the USB device when the USB device is the master device.
