AAO 4.56 b 19 - MSFS
Over the last few weeks AAO sometimes takes a few minutes to start up. Other times it is instant. The hardware hasn't changed at all. All the flightsim hardware is in a powered USB hub.
I've tried various permutations of turning the hub off before and after shutdown, as well as turning the hub on before and after startup.
Also tried launching AAO with no hardware attached. It still seems to be random whether it will load in seconds or minutes.
I have captured 3 logs.
The first one is a slow load with all devices attached. If you look at the time stamps you can see where there are some significant delays.
