Listing 1 USB filter driver example

; This .INF file demonstrates how to install a filter driver
; for a USB device.
;
; The lines marked with the comment "Filter driver install"
; identify those lines that were specifically added in order to install
; the upper filter driver onto the "driver stack" for this USB device
;
; If one were to remove these lines, what remains is the original
; .INF file to install just the one driver for the USB device.
