I would like to ask for help! I'm working with muRata LoRa module what contain STM32L072 microcontroller. I must connect USB to STM32L072, but I can't found correct information how to do that. Maybe someone can share schematic?

Perhaps look at the DISCO or EVAL board schematics implementing USB connectivity
