Summary: defines a device instance that is a member of the device information set

!!!!C# Definition:
 [StructLayout(LayoutKind.Sequential)]
 struct SP_DEVINFO_DATA
 {
   public uint cbSize;
   public Guid classGuid;
   public uint devInst;
   public IntPtr reserved;
 }

!!!!VB Definition:
 <StructLayout(LayoutKind.Sequential)> _
 Private Structure SP_DEVINFO_DATA
        Public cbSize As Integer
        Public classGuid As Guid
        Public propertyId As Integer
        Public reserved As IntPtr
 End Structure

!!!!Fields:
'''cbSize''', Size of the structure, in bytes.
'''classGuid''', GUID of the device interface class.
'''devInst''', Handle to this device instance.
'''reserved''', do not use.

!!!!User-Defined Field Types:
None.

!!!!Notes:
On 32bit platforms, all SetupApi structures are 1-Byte packed. On 64bit platforms the SetupApi structures are 8-byte packed. IE for 32 bit SP_DEVINFO_DATA.cbSize=28, for 64Bit SP_DEVINFO_DATA.cbSize=(28+4)=32.

(Or, is it because the size of the Reserved pointer is 4 bytes vs 8 bytes ?)
