Thanks Kbird

Interesting!
Was checking board again tonight then put it aside but still connected to PC. I decided to start DCS and fly for 1st time in a while. I needed to check a setting on the X52 and when I went to setting I noticed it listed the new board beside the X52!
So I tried to set a switch and it was recognised.

I then decided to check CLOD and setting of a switch identified Joystick1 with a button number - except CLOD starts numbering at "0" and not 1 unlike DCS.
So then checked windows devices and it shows with 8 buttons and they all indicate working - because I thought it would not show without axis I never checked that!
