As Max Krummenacher asked before, tested also Colibri iMX7S NAND version, everything works fine (USB1 is reported as unavailable by the driver): USB0 can be still used in both host/OTG modes.
Colibri iMX7 # usb reset resetting USB... USB0: USB EHCI 1.00 USB1: Port not available. scanning bus 0 for devices... 2 USB Device(s) found scanning usb for storage devices... 1 Storage Device(s) found

Same for UMS:
