MCU board: reroute CRS_DV KSZ8081's pin to GRXDV MCU's pin and with that an USB_OVERCURR flag
CRS_DV pin is now connected to the GCRS pin which is only used in MII mode and not in RMII mode. CRS_DV must be connected to GRXDV MCU's pin. Mistake has been made. The USB_OVERCURR flag must be routed elsewhere because it takes up the GRXDV pin.
