But you surely got a manual for that device!?

Read the manual, it should describe the communication scheme…

The M-Bus Mini Master is in reality most likely the ZETA M-Bus Mini Master modul even if you got it somewhere else. Although I think its price is relatively steep, considering that it is most likely build around this schematic.

Basically this interface should use an FTDI FT232 or Prolific PL2302 chip as USB to serial converter and will then be installed under most modern OSes simply as a serial port. If it is indeed based on such a simple USB to serial port converter, you simply need to implement the M-Bus bit protocol using the VISA functions to access your (virtual) COM port..
