The present invention provides a method, device and system for bidirectional wake-up based on Universal Serial Bus (USB). A first apparatus enters a wake-up state according to the triggering of a wake-up event, and generates a wake-up signal; and the wake-up signal is transmitted to a second apparatus through a USB bus in order that the second apparatus, after detecting the wake-up signal on the USB bus, enters the wake-up state. The first apparatus is a Mobile Internet Device (MID) host, then the second apparatus is a wireless module; or the first apparatus is the wireless module, and the second apparatus is the MID host. The method, device and system in the present invention enable the MID host and the wireless module to detect the USB bus signal respectively, and perform sleeping or wake-up according to the USB bus signal. Not only the MID host can wake up the wireless module, but also when the MID host and the wireless module are both in sleeping states, the wireless module can wake up the MID host through the USB bus after being triggered to be wake-up. |
