VB Signature:

Declare Function CM_Get_DevNode_Registry_Property Lib "setupapi.dll" (TODO) As TODO

User-Defined Types:

None.

Alternative Managed API:

Do you know one? Please contribute it!

Notes:

In most cases you can use SetupDiGetDeviceRegistryProperty.

Also Microsoft.Win32.RegistryValueKind only contains enumerations for the basic kinds.

Tips & Tricks:

Please add some!

Sample Code:

// The following code shows how to grab the parent device's driver name. The devinfo_data.DevInst is
// from SetupDiEnumDeviceInterfaces and SetupDiGetDeviceInterfaceDetail so please see those examples

string driver_name;

uint parent;
if (CR_SUCCESS == CM_Get_Parent(out parent, devinfo_data.DevInst, 0))
{
   Microsoft.Win32.RegistryValueKind kind;
   uint length = 0;
   CM_Get_DevNode_Registry_Property(devinst, CM_DRP_DRIVER, out kind, IntPtr.Zero, ref length, 0);

   if (length > 0)
   {
     IntPtr buffer = Marshal.AllocHGlobal((int)length);
     if (CR_SUCCESS == CM_Get_DevNode_Registry_Property(devinst, CM_DRP_DRIVER, out kind, buffer, ref length, 0))
       driver_name = Marshal.PtrToStringAnsi(buffer);
     Marshal.FreeHGlobal(buffer);
   }
}
