I would like to deploy a .inf based USB driver with my installer.
I guess the .inf needs to be placed in %SystemRoot%\inf
, but there is also a .cat (WHQL certification I guess?), and .sys files. What do I do with those?
EDIT: Resolved, thanks to the helpful answers. I was able to P/Invoke the function, so I have a post-install action which runs the following code:
namespace DriverPackageInstallAction
{
static class Program
{
[DllImport("DIFXApi.dll", CharSet = CharSet.Unicode)]
public static extern Int32 DriverPackagePreinstall(string DriverPackageInfPath, Int32 Flags);
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
DirectoryInfo assemblyDir = new DirectoryInfo(Application.ExecutablePath);
DirectoryInfo installDir = assemblyDir.Parent;
int result = DriverPackagePreinstall(installDir.FullName + @"\Driver\XYZ.inf", 0);
if (result != 0)
MessageBox.Show("Driver installation failed.");
}
}
}
