The only thing that bothered me is that the driver is not available as a standalone download: You need to download a 50MB installer, which then downloads another 150MB: DirectX, the .NET framework and other components required for the (useless) software. Without network connection, you cannot install the driver.
I have found that you can download two small cab packages:
http://download.microsoft.com/download/C/B/8/CB8414CD-487E-4E18-8B24-DA8ED722C770/ReleaseCatalogMsi.cab http://download.microsoft.com/download/C/B/8/CB8414CD-487E-4E18-8B24-DA8ED722C770/ReleaseCatalogSetup.caband find the URL for your language and OS inside the xml files included in cab files.
but i haven't found the silent switches (if any) for setupstb.exe
