OK so updated to 10.11 beta 12. G920 recognised in controllers. When enabled it constantly scrolls mouse down. I disabled it then cleared all mappings and that stopped the scrolling. When to map buttons and it does not recognise any inputs. I think it still needs work.
I'm running w10 IOT LTSC, ver 1809, Logitech driver is 8.85.75.0 and Logitech gaming software 9.02 if that helps.
