You probably need to install your motherboard's official chipset drivers. I've heard of people having problems with USB/USB-based devices such as internal card readers, and it turns out they were just using the ones built into the windows 7 installer. After installing the motherboard's manufacturer's official drivers intended for Windows 7 the problems were solved.
