Chandrakant,
Drivers for USB devices is created above the USB Hub driver or USB
Generic Parent driver, depending on the quantity of interfaces your
driver had. These drivers are resposible to send URB to the devices and
it deffer each other by using a pipe handle that is associated with each
interface when your driver call UsbBuildSelectInterfaceRequest in order
to configure your device to use it.
See “Selecting the USB Device Configuration” in DDK.

Fernando Roberto da Silva.
