Windows 8. Scan for Hardware Changes not working

NTDEV
1

Hi All

I am installing drivers for a USB device through an application. I
call SetupCopyOEMInf() in the application followed by
CM_Reenumerate_DevNode() to load the drivers. The device is plugged in
before running this application. This solution is working fine in all the
OS’s (WindowsXP, Vista and Windows7) but it doesn’t work in Windows 8
Release Preview. On Windows 8 release preview clicking on Scan for Hardware
Changes is not working. After the installation application finishes, I need
to unplug and re-plug the device to make the drivers load. What could
possibly be going wrong. Is this because it is still a Release Preview
version so might not have full fledged PnP functionality implemented as
opposed to a commercial release? Or is there any other factor I should be
aware of?

Thanks in advance.

Did you look at the setupapi.dev.log to see if the install was even attempted? Perhaps something is wrong with the INF. Consider using dpinst instead, installing it as driver package might yield better results.

Hello Doron. I saw the setupapi.dev. Drivers installation is being
attempted. But after the application finishes driver installation, clicking
“Scan for hardware changes” in the Device Manager is not loading the
installed drivers in Windows 8 while the same is working for all the other
OS’s upto Windows 7. If I then unplug the device and re-plug it, then the
drivers get loaded without any problem so there shouldn’t problem in the
INFs.

Thanks
