1. Make sure the VBUS is on at your S3 status, the mouse's LED is should be on.
2. make sure your mouse is remote wakeup featured.
3. Make sure the wakeup is enabled from the roothub to mouse.
For example, if your mouse is at bus 5(using lsusb to get), and there is a hub at this
bus, the mouse is connected one of the ports.

echo enabled > /sys/bus/usb/devices/usb5/power/wakeup (roothub)
echo enabled > /sys/bus/usb/devices/5-2/power/wakeup (hub)
echo enabled > /sys/bus/usb/devices/5-2.1/power/wakeup (mouse)
