The device tree contains information about the devices present on the system. When the computer starts, the PnP manager builds this tree by using information from drivers and other components, and updates the tree as devices are added or removed.
When a bus driver detects an arrival or removal of a child device, it reports that to the kernel-mode PnP manager. You should avoid using the compatible identifiers listed in the right column. USB devices with multiple functions are called composite devices. After querying the hub driver for the hardware IDs associated with the new PDO, the system searches the appropriate INF files to find a match for the identifiers. The Generic Parent driver then creates a separate set of PDOs one for every interface with a separate set of hardware IDs for each interface of the composite device.
The class code, subclass code, and protocol code are determined by the bInterfaceClass , bInterfaceSubClass , and bInterfaceProtocol fields of the interface descriptor, respectively. Note If you are providing an INF, either to load your driver or to provide a friendly device name, your hardware identifiers should match the bold identifiers in the left column of the following table. Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update.
You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how:. If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.
