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) > Thanks, > Don > > -- > To unsubscribe from this list: send the line "unsubscribe linux-usb" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
