    Fixed but fail too.

    #if USB_SOF_EVENT
void USB_SOF_Event (void)
{
  /* Payload header - SOF_Event_Buf[0~1] */
  if(JPG_Cnt == 0) /* Start of Frame */
  {
    SOF_Event_Buf[0]  = 0x02;
    SOF_Event_Buf[1] &= 0x01;
    SOF_Event_Buf[1] ^= 0x01; /* FID */
    SOF_Event_Buf[1] |= 0x80; /* EOH */
  }
  else
  {
    /* The last packet of jpg */
    if((JPG_size - JPG_Cnt) <= (EP3_MAX_PACKET - 2))
      SOF_Event_Buf[1] |= 0x02; /* EOF - End of Frame */
  }

  /* Copy data and send */
  Write_To_Buf();
  USB_WriteEP(0x83,(BYTE *)SOF_Event_Buf,Buf_Size);
}
#endif
