| 873 | Here and above you man do a partial usbd_copy_out but then skipping the remainder. Is that save or will that confuse some other logic in case of a failing condition + "goto"? Should you do all the conditional checks first and then do the usbd_copy_out() all together? | |

| 873 | I can't do any checks before data has been copied out of DMA-ble page cache. So I prefetch header to private on-stack memory to not thrash caller-supplied buffer on negative case, than do all the checks and than copy out all data to the buffer on success. | |
