It came down to startup issues. If every fifth time the system was turned on it
wouldn't initialize properly and not see an airflow or whatever sensor, it
required the calling of a tech from the test group to come over and get it

Why the proscription against USB?
Because of difficulty with USB device drivers? Or the plethora of serial port
emulators that have unforeseen interactions with software that thinks it's
talking to a real serial port? or what?
