Qu Qu Troubleshooting

I noticed on my SQ if I pull the USB the desk notices and shows such…

plugging in the usb and the desk sees and responds

my new QU5 hangs.

doesn’t notice if I pull card or card

looking at the usb utility without either card or usb plugged in and board reports capacity, used, unused as if those two devices are plugged in

inserting a different usb, the numbers remain the same

and

I can’t format the usb

turning the unit OFF and cold booting resolves the recognizing and formatting but still can’t record even though signal is available (per the meters) to the 2 ark AND multitrk

I can’t tell for sd card, but the usv Stick is hotplugable. I did it several times with different usb sticks (to backup shows and other settings). No problems.
