I have this board here:
STM32F103C8T6 STM32F030C8T6 APM32F103CBT6 ARM STM32 Micro TYPE-C System Development Board Modul:

Attaching it to USB I get (Linux) the following message (see below).
Is that normal and I need to access it via the 4 pins to an external USB-Uart interface (3.3V/GND/SWIO/SCLK) ? I do have such thing, but it seems to provide only 3 pins.
So USB is just for power supply here, right?
