Did you ever try to identify devices in your device manager that have a yellow icon ? Devices with yellow icons are unknown devices that give you almost zero information about the type of the device. The freeware Unknown Device Identifier displays a list of unknown, disconnected or old devices with information about each of those devices.
Each device contains information about the manufacturer, OEM name, device type, device model and even the name of the device. It is therefor easy to identify the device and right-click the device to search for drivers for the device or contact the vendor using the program itself.
It would not be a problem however to use a normal search engine to find a driver instead of the build in search. The biggest problem that I see is that a lot of devices are shown and it could be quite complicated to find the correct one that corresponds to the yellow icon in the device manager.
