The operating system loads the Microsoft-supplied keyboard driver to manage the keyboard interface, and the Microsoft-supplied power keys driver to manage the power keys interface. The USB generic parent driver enumerates each of these interfaces as a separate device. For example, a composite USB keyboard with power buttons might have one interface for the keyboard and another interface for the power buttons. The interfaces of some composite device operate independently. Using the features of the generic parent driver, device vendors can make selective use of Microsoft-supplied driver support for some interfaces. In Microsoft Windows XP and Windows Me, this facility is streamlined and improved by transferring it to an independent driver called the USB generic parent driver (Usbccgp.sys). Microsoft Windows 2000 and Windows 98 operating systems include a generic parent facility in the USB bus driver (Usbhub.sys) that exposes each interface of the composite device as a separate device. In USB terminology, these devices are called composite devices. Many USB devices expose multiple USB interfaces. This section describes the Usbccgp.sys driver provided by Microsoft for composite devices.
