If you test driver installations quite often under Windows 7, then PnPUtil from Microsoft can be quite useful.
The RAPR GUI driver store management utility can also help easily identify the inf associated with a driver.
Note that PnPUtil has a bug under Vista that output redirection does not work and it affects RAPR as well. Travis, of libusbK, and libusbDotNet fame has a console version of of driver store management utility located here. The download includes the source as well.
Those who are interested can probably enhance it and create a GUI version for it. Do not use it under XP though.
