Does anyone know what USB.OnDevicesChanged is? It’s giving me lag spikes in the editor.
Thanks!
I’ve got exactly the same problem - have you found a solution?
No… I still haven’t even figured out what they are… 
I wanna say they stopped on their own? It’s possible I just moved on to a part of the project where they’re not happening.
Fuckin’ Unity problems…
I have a logitech keyboard (G19) that has a miniature screen (not that it was even used or that it had any drivers installed) when I unplugged it, the unity stopped lagging… do you have a oculus rift or multiple monitors or even just a keyboard like mine?
I have 3 monitors, all of which have built-in USB hubs, most of which have at least 1 thing plugged into them. One has a webcam permanently connected, another is frequently used to connect flash drives and controllers. I also use an external USB sound card, and sometimes have an arduino connected over usb. If it is a problem with a specific usb device, any one of them could be the culprit.
I have an old DK2 but don’t keep it connected. My keyboard is a fairly mundane WASD mechanical, but interestingly I do use a Logitech G502 USB mouse.
