发明名称 Advanced power management in generic USB drivers
摘要 Techniques are disclosed to provide advanced power management in generic USB drivers. More particularly, a generic USB device driver architecture is described which enables development through a user-mode USB library that accesses a generic kernel-mode driver. The architecture may be utilized to provide advanced power management. In a described implementation, a method includes defining a power management policy for a device plugged into a computing system and utilizing the defined power management policy to determine when the device enters a suspend mode. Once the device enters the suspend mode, the method allows the computing system to enter a lower-power state. In a further described implementation, the power management policy is defined through a plurality of routines provided by a generic user-mode library (e.g., a dynamic link library (DLL)), where the generic user-mode library is communicatively coupled to a kernel-mode generic device driver.
