Ok, i just fixed the last three bytes in the bulk-out transfer problem. Please see below for the log. Now the last three bytes are read correctly. After SCSI_WRITE_10 is received, the gadget driver prints "g_file_storage gadget: disconnect or port reset", it means USB reset interrupt is received by the UDC driver. I don't know why USB reset interrupt is triggered.
