Okay so if my device is made by the Microsoft Hates Me Corporation of Tokyo, then maybe I can understand why MS don't go out of their way to provide a working search facility for the drivers (although they should, if you ask me).
But tonight I attempted to install a Microsoft VX1000 web camera, that is to say, a web camera MADE BY MICROSOFT, and when Windows said "Oh! sorry, dunno what this is, want me to search for a driver?" and I said "Hey, yes mate, go for it!" I had the faintest, vaguest hope that MAYBE it might find some drivers.
No such fucking luck.
Not only did it not find them, but when I went to the MS web site, then the download centre, and searched for "VX1000", you know, the NAME OF THE PRODUCT, it returned zero, no, none, zilch, results.
I fucking despair, I really do.
