STM NUCLEO-F207ZG Board not detecting in a specific USB port

I have a STM NUCLEO-F207ZG board. Yesterday it was working fine on (say) USB port 1 on my laptop. Today, It gets powered via USB port 1 , but isn’t detecting my board. But When I reconnect it via (say) USB port 2 , it works fine. I also tried using another device on USB port 1 (SanDisk 32GB pendrive). It works fine. I don’t understand why my STM board is not working on a specific USB port (1) .
The board is functional, it works fine on any other USB port but not on USB port 1.

How shall I solve this issue?
