+Warning:
+    The board is blacklisted because it uses `stdio_cdc_acm` as STDIO, which needs
+    a CDC ACM interface in addition to the CDC ECM interface, but the number of
+    available endpoints is not sufficient for this. To use this application you
+    have to use `stdio_uart` or any other `stdio_*` module, for example:
+
+    USEMODULE=stdio_uart BOARD=$(BOARD) make -C tests/usbus_cdc_ecm
+
+endef
+
+ifneq (,$(filter $(BOARD),$(BOARD_BLACKLIST)))
+  $(info $(_usbus_cdc_ecm_blacklist_info))
