USB Dropouts with Arduino Button Box

Hello people!

I have built myself a driving simulator rig with new computer from scratch, and since im using a ready-to-use Arduino Buttonbox with built-in LED and LCD Display, i always had weird dropouts with it. The Box is programmed for SimHub so i think it has something to do with it.

I have tried everything on the computer side (drivers, powered hub, etc.). When i close Simhub and just use the box without the screens only for button inputs, everything works fine and I have no dropouts what so ever but when I let Simhub run so the Displays work, with gear number and infos running, the box drops out randomly and quite often.

I could post some Logs if needed. 

Thanks in advance for any help
