This code is identical to v3.
In another thread in some other iteration, you stated "I need the terminated '\0' character. Since it'll be sent by USB driver. Without this, the last character will dispear."
Overall, I am very reluctant to accept this entire mechanism for retrieving strings, unless you can explain why this extremely roundabout way of putting a string into a buffer is necessary.
But this also requires going back and replying to my comments on 2/5.
