I've already submitted apologies I should have included that in my post - FB23524998 Per my example adding PID is potentially problematic, in my testing it's not reliable, as noted in the original post. Though, if VID is unchanging it wouldn't be a terrible idea append that to serial. That way you'd avoid collision in the case that multiple vendors somehow assign the same serial number to two distinct products.
