Assigning raw mode to PDO in KMDF problem.
in [Device Drivers]

From: Doron Holan [MS] on 13 Aug 2006 14:46 you can try,but the UI treats these values differently from OS to OS set DEVICE_CAPABILITIES::SilentInstall and NoDisplayInUI and also set PNP_DEVICE_DONT_DISPLAY_IN_UI in query pnp device state (this last one is only required for a raw PDO) in KMDF, if you set NoDispalyInUI in your WDF_DEVICE_PNP_CAPABILITIES for a raw PDO, KMDF will also report PNP_DEVICE_DONT_DISPLAY_IN_UI in the pnp state. d -- Please do not send e-mail directly to this alias. this alias is for newsgroup purposes only.
