that message can probably be ignored, if you are running libmaple core go into
Arduino_STM32/tools/linux/stlink
try out things like st-info --descr etc, it should be able to detect your st-link dongle
and that dongle should show up in lsusb
preferably get updated version of the st-link utilities
https://github.com/stlink-org/stlink
it may be available in your repositories or build that from source (preferred)
the st-link binary shipped in the core is rather old, the new ones has st-link --probe which would detect the st-link and the connected stm32 etc
