Unknown USB device

I've recently formatted and installed Win 8.1, done all windows updates and everything is running fine however, this little thing in device manager is bugging me...

My spec is in sig. Any idea what I need to install to get rid of it?

Ah, it just so happens that I recently tidied my case a little as I fitted a new hard drive and gfx card. So some things may have been disconnected and reconnected in the wrong place, gonna check now...

EDIT: And that indeed was it, thanks.
