    Unsigned PnP Driver Install?

    I'm trying to write an application using WDK to install an unsigned driver for a USB device, so that the user can plug in the device and not have to manually click through the Found New Hardware Wizard. I've tried calling SetupCopyOEMInf(), DriverPackageInstall(), and DriverPackagePreinstall(), and no dice. The drivers install, but I still have to go through the Found New Hardware Wizard when I plug in the hardware.

    Is it possible to fix this, and if so, could someone point me in the right direction?

    Thanks in advance.

    saw ur question when i was searching for an API to do the Driver install from Windows Update.

    I think the DDK function "UpdateDriverForPlugAndPlayDevices" will help you. I'm not sure but please give a try.

    No it is not possible to install drivers with out pop up... when ever INF or SYS file changed.. its need to go WHQL certification.. then only it can be installed without pop up
