In order to utilize the management USB on the device, I had requested and received the required firmware.

It worked as intended(by issuing pl/ph via ACM1 - connected to COM express SER0 console) however, stopped reading inputs from the usual serial port that I had been using. As a result, I tried shutting it down completely (removing power) and booting it again via the port mentioned above.

Now, one of the ports (ACM0 - virtual com port; from the documentation provided) is not appearing and (ACM1) is not working either although the connection from the device is visible.

Am I missing something?

When you power down the board, you also need to unplug the USB cable to the stm32. The on board micro-controller can be powered standalone from the USB connection.
