It means that you may have possibility not be able to wake up the system from S3 or S5 by the USB device. This is because the USB EZ Charger port provide 3 times current than general USB port for consumer products like iPhone, iPad and iPod touch that need large amount of current for faster recharging within less time. To avoid this kind of symptom, please attach the USB keyboard and mouse to the general USB port to obtain the expected behavior.
