MKR Zero board and the port

[weal5300]

MY MKR Zero board doesn't appear when I plug it in the USB port. What should I do?
I used another MKR Zero board in other pc, and I have got the same problem.

Make sure the USB cable is completely plugged into both the Arduino board and the PC.

You may have a damaged/defective or charge-only USB cable. Try a different cable.
