physical  hardware keyboard layout - how to get information about it

I am looking for a way to get information about physical hardware keyboard layout - not the one which can be configured in Windows OS. I looked at Win32_Keyboard wmi class by:
Get-CimInstance -ClassName Win32_Keyboard -Property *
In output there is a: 
Layout : 00000415
but this one is reflecting OS setting, can be changed to any other layout, this is not about physical  

Anyone?:)
