I have ASUS x5520ld with windows 7 64 bit oS, and of course as many laptops mine too has 2 usb ports, so i bought the cooling pad with usb connection but it also has that external usb port to compensate for occupied one. i have mouse and keyboard too, but whenever i put mouse or a keyboard into that external usb port from cooling pad they won't work. The problem is that i need all 3 of those components, does anyone know how to fix this?

Actually ports do work with keyboard and mouse but when i try and plug cooler usb and when i plug something else in the coolers compensation usb hub it won't work, laptop probably cannot recognize more that 2 usb ports
