Hi,

I am trying to find a way to install a usb modem driver, in form of single
..inf file.

When I attach the USB device to PC, it will prompt for the device.
I want the driver to be installed automatically without requiring user
interaction during install.

I copied the file to %systemroot%\inf and it seems like it finds it and
installs something. But I think there are multiple steps required because it
still prompts the user. When I select "let windows search for driver", it
finds the driver. Then when I press "Next" to install, I get warning that
the driver is not logo tested (signed).. if I choose to continue anyway,
everything gets installed OK.

Now, I want the above process to happen silently. Can this be done? How?

I tried LaunchINFSectionEx function exported in advpack.dll as part of
InternetExplorer, but it's not working:

LaunchINFSectionEx(NULL, NULL, _T("C:\\Windows\\inf\\usbmodem.inf,,,36"),
0);
