That precision is an illusion. These packages are often shotgun attempts to cover many chipsets and vendors. A single driver archive may contain several INFs, COM utilities, and a confusing set of installer options meant to coax Windows into recognizing a variety of devices. Sometimes they work; often they don’t. Even when a driver gets a device to enumerate, functionality can be partial—no audio, unstable capture at higher resolutions, or flaky frame rates. Worse, hidden incompatibilities with newer OS releases can render old solutions useless or unstable.
