There are some well documented issues with timing and USB that have been

Sure, the timing isn't really , really predictable (8kHz frame rate and

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?
