Have you tried turning off all power management for usb devices within the device manager? Don't forget the 'Human Interface Devices' section. I missed one there one and it caused problems with an Arduino project I was working on.
EDIT: Nevermind, i see someone else suggested already.
@Reset XPDR Is there a download link that I missed or should I message you?
EDIT -- found it. Thank you! https://drive.google.com/file/d/17pQdqAe2wl1Kf-GcEQVIZfQZudubNnWu/view
This is probably a dumb question but.... How do I know it's working? Does it auto-start with MSFS or do I need to run it manually? I do see that it's running now in the task manager, but I'm up at FL430 and there doesn't seem to be any difference. I suppose that could be normal as well though..
