WebThe driver itself chooses what devices it supports. It does this programmatically, i.e. by checking the device's vendor and product ID, or, if those aren't available (e.g. an old device), performing some auto-detection heuristics and sanity checks. Once the driver is confident it's found a device it supports, it attaches itself to it. WebPlatform devices ¶. Platform devices are devices that typically appear as autonomous entities in the system. This includes legacy port-based devices and host bridges to peripheral buses, and most controllers integrated into system-on-chip platforms. What they usually have in common is direct addressing from a CPU bus.
