Yes. 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.
