Since there isn't a "device ID", only a "Model ID", there isn't a new compiled version for everything being shipped. There's maybe 3 or 4 versions of the software total and there's probably one version that's more prolific than the others.
He may not have been able to buy one of those USB Microphones off of Amazon that had the same VID and PID but the old model that he repaired is one of the few versions that the manufacturer used so there's a pretty decent chance that the fixed one will work as is with another computer with the software on it.
