摘要： If a USB device is turned off or is not active, the device may be electrically disconnected from a USB host controller. The device may be electrically disconnected through a physical interface on the device. In some embodiments, if the device becomes active during a wait period (e.g., 2-3 seconds) prior to electrically disconnecting the device, the device may not be electrically disconnected. In some embodiments, when the device is electrically disconnected from the USB host controller and no system activity of a bus mastering peripheral is occurring, the CPU may enter a low power state if other conditions are met. In some embodiments, if the USB device becomes active after electrically disconnecting, the electrical disconnection may be discontinued.
摘要翻译：如果USB设备已关闭或未激活，则设备可能与USB主机控制器电气断开。该设备可以通过设备上的物理接口电断开。在一些实施例中，如果在电气断开设备之前的设备在等待期间（例如2-3秒）期间变得有效，则该设备可能不会被电断开。在一些实施例中，当设备与USB主机控制器电气断开连接并且没有发生总线母盘制作外设的系统活动时，如果满足其他条件，则CPU可以进入低功率状态。在一些实施例中，如果在电断开之后USB设备变为有效，则可能停止电断开。
