hi all: We are trying to make usb hibernate work on our embedded system. below are configs we enable for system power management: # # Power management options # CONFIG_SUSPEND=y CONFIG_SUSPEND_FREEZER=y # CONFIG_HIBERNATION is not set CONFIG_PM_SLEEP=y CONFIG_PM_SLEEP_SMP=y # CONFIG_PM_AUTOSLEEP is not set # CONFIG_PM_WAKELOCKS is not set CONFIG_PM_RUNTIME=y CONFIG_PM=y CONFIG_PM_DEBUG=y CONFIG_PM_ADVANCED_DEBUG=y CONFIG_PM_SLEEP_DEBUG=y # CONFIG_APM_EMULATION is not set CONFIG_PM_CLK=y CONFIG_CPU_PM=y CONFIG_ARCH_SUSPEND_POSSIBLE=y CONFIG_ARM_CPU_SUSPEND=y When we use "echo mem > /sys/power/state" , we didn't see any function in usb_device_pm_ops is called. Did we miss any configuration to let hibernate work? Or we used the wrong way to activate it?
