That is not expected behaviour and might be an indication of damaged hardware. I'd suggest to reinstall the OEM firmware and check the situation there, also by testing all of your USB ports, you might want to return/ RMA your device while you still can (even if you don't plan to use USB now).

Edit:
Also check the USB ports with a flashlight and a magnifying glass for dirt, debris or bent contacts.

In case the OEM firmware works (I doubt it, that issue looks like physical damage), re-flash the OpenWrt factory image (19.07.0 or @hnyman's master builds) via tftp and check again.

Thank for support.
In version 18.x.x also had the same problem, so I think it is not due to version 19.07.
I will check it with the default FW and report back later.
Since it's a new router, I can change it because of the amazon prime account

At FW OEM, cannot use usb port. It was broken, and I changed a new router. Everything worked fine when I installed openwrt 19.7 on the new router.

Thanks for the help.
