    Public ClassGuid As Guid
    Public PropertyID As Integer
    Public Reserved As IntPtr
    End Structure

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.
