DRIVER_SETTINGS Problem

Feb 3, 2009 at 5:51 AM
In the source code while going through USBInstallDriver I found a line
USB_DRIVER_SETTINGS lpUsbDriverSettings = { DRIVER_SETTINGS }

DRIVER_SETTINGS has been defined in WebCam.h as
#define DRIVER_SETTINGS \
                                sizeof(USB_DRIVER_SETTINGS), \
                                USB_NO_INFO, \
                                USB_NO_INFO, \
                                USB_NO_INFO, \    
                                USB_NO_INFO, \
                                USB_NO_INFO, \
                                USB_NO_INFO, \
                                USB_DEVICE_CLASS_VIDEO, \
                                USB_NO_INFO, \
                                USB_NO_INFO


Can somebody of you plz help me understand what does this imply and how is this significant..
