Windows installs multiple drivers for this device. This is the 2nd driver (that's failing to install). The first will be listed under USB in Device Manager. By default, Device Manager only displays a device when its connected.
Plug in/remove your device and look for a device appearing/disappearing under USB. It'll probably be a USB Mass Storage device. (Maybe a USB Composite). When you find it, right click it Properties->Details tab. Use the pull down menu to select Hardware IDs. Copy/paste what you see in your next post
