In the SonyDcam.inf file which is found in the DDK WDM samples, there is a
comment in this file in the ControlFlags section ....

[ControlFlags]
; All PnP devices should be excluded from manual AddDevice Applet list
ExcludeFromSelect=*


I found a reference to this section which mentions that for the NT-based
operating system, the specified devices ( all if * is specified) will not be
displayed by the Add Hardware Wizard, but will be displayed by the Found New
Hardware and Hardware Update wizards.

My question is why would you NOT want to display PnP devices in the Add
Hardware Wizard but allow them to be displayed in the Found New Hardware and
Hardware Update wizards?

In article <u1gGsAYoEHA.648@tk2msftngp13.phx.gbl>, hjohns1@ix.netcom.com
says...
Not a good idea. The default (ExcludeFromSelect missing from inf file)
ought to be equivalent to ExcludeFromSelect=*.
