I can't use any USB mouse which supports Remote Wakeup to wake up the system by default. If I enable the wakeup node in /sys/bus/usb/devices which is disabled by default, the mouse can wakeup the system successfully. Clearly, the only thing I can do is to register the wakeup source for USB Mouse devices. -- Regards, Michael Wu
