A client driver for a composite device is no different from a client driver for a non-composite device, except for its location in the driver stack. For a composite USB device that exposes multiple functions and does not have a parent class driver, Windows loads the USB generic parent driver Usbccgp. The parent driver creates a separate PDO for each function of a composite device. Client drivers FDOs for functions are loaded above the generic parent driver.
Vendors might choose to provide a separate client driver for each function. A USB client driver can run in either user mode or kernel mode, depending on the requirements of the driver.
Microsoft provides the following helper libraries to help kernel-mode drivers and applications to communicate with the USB driver stack:. Microsoft provides the Usbd. The helper routines simplify the operational tasks of a client driver. This helper library is new for Windows 8.
The library exports routines primarily for allocating and building URBs. Those routines replace some of the legacy routines exported by Usbd. The new routines require the client driver to register with the USB driver stack, which maintains the handle for registration. That handle is used for calls to other Usbdex. Skip to main content.
