When Windows' Device Manager just can't seem to give you information about a piece of hardware, free, open-source utility UnknownDevices will point you in the right direction, allowing you to find the necessary drivers to get it up and running.
Generally, when you install a new device, you know what it is and where to find drivers, but if you've just done a clean install of Windows, for example, it can be difficult or time-consuming to determine what your many "unknown" devices in Device Manager actually are. Luckily, UnknownDevices is a portable app that can quickly give you more information about the manufacturer and model of those unknown devices to help you on your hunt for the necessary drivers.
UnknownDevices is a free download, Windows only.
