Pixhawk Cube doesn't connect via USB

I got 2 cube orange, one of them is working fine without any issue but the other one doesn’t seem or connect nowhere (in linux there is no dev\ttyUSB, in windows no device in device manager). when I plug usb cable side of the cube block there is only solid green light. I switched cube’s the carrier boards working fine. the problem probably on the cube part.

Which firmware did you use?
