STM32H755 dualcore, I can't start USB_HOST on both cores at the same time

When I boot on core CM4 HOST USB HID at the same time and boot on come CM7 HOST USB MSC

, there is a conflict with USBH_StatusTypeDef USBH_Init (..); (usbh_core.c) this is executed twice.

both core link to these Core files.

Is this a bug, or do I have to fix it with an HSEM handler
