ok,the gentleman helped me to be able to activate my trim wheel and all was well,then i broke the throttle,talked about in another thread) and i got the new throttle hooked up,NOW the trim wheel shows as an unknown controller,the red light is on,and the pc makes the noise when i connect the USB,and as i said its as an unknown..so do i need to uninstall all of my controllers? and start all over?.do i need to remove P3D? i had installed the two part uninstall/install for that V4 update ,then did it backwards again..maybe that was it?..the reason i switched back was none of the controllers worked in the update..mater of fact now i say it,they were all showing as unknown...only the trim wheel continues to not work,one more thing..the trim wheel shows as a windows 7 only item,with no compatibility .
