Abstract
An adaptive universal serial bus (USB) charging method and system are disclosed. In a low-power state, a USB device is charged with a non-USB charging mode. The non-USB charging mode is retained when no variation of a data signal coupled to the USB device is detected. When the data signal possesses variation for a first period, it is switched to a third proprietary charging mode.
