                                                      This may well work
                                                      better. I have to
                                                      admit that I have
                                                      never studied the
                                                      difference between
                                                      shared usb buses.
                                                      My thought was to
                                                      try to change the
                                                      connected usb
                                                      devices, but
                                                      tested first the
                                                      only free usb3
                                                      port (blue) on the
                                                      add-on frontpanel
                                                      of the
                                                      workstation. The
                                                      other two usb3
                                                      ports are on the
                                                      backpanel and are
                                                      used for the Asus
                                                      blu-ray burner and
                                                      8TB Seagate
                                                      expansion video
                                                      disc. <br>
                                                      <br>
                                                      The other usb
                                                      ports on both
                                                      panels are usb2
                                                      ports, whereof two
                                                      for the wireless
                                                      keyboard and mouse
                                                      on the fronpanel.
                                                      What I possibly
                                                      already have
                                                      mentioned before,
                                                      is that sometimes
                                                      if I connect a
                                                      usb(2) device or
                                                      memory to the usb3
                                                      port on the
                                                      frontpanel, this
                                                      cause hang on the
                                                      keyboard or mouse.
                                                      But this didn't
                                                      happend this time
                                                      with the USB3
