I am a computer engineer and I will love to help you on this. You can easily download the host controller driver only for your Window 7 64 bit. There are lots of free software providing websites that are available in the market which provides the USB host controller driver for absolutely free. The websites that I usually visit are the Softonic, scanwith, download.cnet, softpedia, in.norton, freedownloadcenter, soft82. Youhave to just visit these websites and search for your USB host controller. Now you have to just click on the downloading link. It will take few moments only to download the driver. Some of the website provide the compressed or the zipped software so for that first of all unzip them or extract them without getting panic. After that simply install them on your computer by clicking on the setup. Hope these information comes good for you. It was really nice to help you.
