If USB-BLASTER uses non-volatile memory, based on the security perspective, they cannot use USB-BLASTER. Then, we have to submit the certificate of not used non-volatile memory. Or even, it is difficult, we need to show the evidence that USB-BLASTER doesn't have non-volatile memory. We are requested to show it by tomorrow morning that is Japan time. I know it is too soon, but we need it as soon as possible.
