The power required by the ipad is greater than most laptops can produce because it has bigger batteries . Exceptions are some of the Macs and some PC's that support higher voltage devices like hard drives etc

That is why one needs either a dual usb cable or a powered hub with high out put.
I am curious why do you need to charge the ipad from the lap top when you need to charge the laptop from power any way. The ipad charges fine from direct power lasts 10 to 12 hours just charge it when you sleep.
ASUS Ai Charger software works fine.
Makes your computer's USB port supply high enough power to iPad so it gets charged.
Nice find! I have asus mother board... :-)
