The peak indicators of ur22c are blinking constantly. Interface doesn't work

Hello friends. For about two years it worked properly. Then suddenly i had such problem. Peak lights are flashing constantly. One after another. Nothing is connected. I tried to change usb cable and computer, reinstall driver etc. No result. Please give me some advice.

Удалось ли найти ответ? У меня то же самое…
Has the answer been found? I have the same thing…

Mine was doing this while it was upgrading the firmware.
Could it have been updating when it was disconnected?
