Alienware 14: Unknown Device in Device Manager

I received my new system and installed a 250 GB mSata card into it and reloaded Windows 8.1 on it. I now have an unknown device in the Device Manager. I installed all drivers, as far as I know, on the disk that came with the system. I still cannot seem to get rid of this error. Anyone go through this process who might know what this is, and what driver I need to install to correct it?
