I am running the OpenBuilds Control software on the Centos Linux operating system. My machine is working well. But when the machine is stationary for a few minutes, it gives a message about the port and disconnects. Is there a setting to prevent this or any other advice?
It's not CONTROL related, its your OS shutting down USB ports to save power Can't help you with the CentOS specifics of how to fix it, but in Windows, that's called USB Selective Suspend, and is part of the motherboard power management: See docs:blackbox:install-windows-selective-suspend [OpenBuilds Documentation] - Linux calls it USB Autosuspend - that should be enough for you to go from to look for how to disable USB sleep/power management under your linux distro too, for example centos usb autosuspend - Google Search
