Hi @rahuj.1
USBH could use port0(USB_DP1/DM1 pins), this is the case on our EV1 and DK2 boards, and in addition also on port1 (USB_DP2/DM2 pins).
Please refer to https://wiki.st.com/stm32mpu/wiki/USBH_device_tree_configuration#DT_configuration_when_using_port0
or
Note that OTG cannot be 'routed' on port0 (USB_DP1/DM1 pins). OTG high-speed is only possible on port1 (USB_DP2/USBDM2 pins) which is mandatory for flashload (e.g. with CubeProgrammer)
For possible HW choices around USB, please refer to AN5031.
