USB port not recognized

    • USB port not recognized

      Hello,
      I have Dreambox DM800hd se newnigma2 v3.1.6 installed. On lower USB port is connected USB flash drive and it is recognized by system. But when I try to connect it to upper USB port, light on USB flash drive flashes, but system does not recognize the device.
      Do you have any idea, what could be wrong? Maybe dead USB port?
      Is it possible that this is problem with newnigma2 firmware?

      Please help .
