I have connected the STM32 USB connector to my Linux PC. lsusb show this port as:
VID/PID: 0x0483/0xdf11 STM32 Defive in DFU Mode
Application specific interface.
It seems that the STM32 on the module responsible for system management and fan control does not have a valid firmware. I still can boot Linux and everything else seems to work fine, also the second port with the serial console.
Is this behaviour expected, or do i need to install a firmware on the STM32?
