                            This may well work better. I have to admit
                            that I have never studied the difference

                            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 capture stick.<br>
