Isn't there always a catch? Updating a driver depends on what the driver need to install and more. Since all files and registry entries can be changed via a command line it's possible to install a driver from the command line.

HOWEVER, are you into Windows deep enough to use tools to reverse engineer a driver install if the maker of the device won't supply those details? I find most Windows NT users to be either ready or not ready. I can't tell from your short post.
