The Rockchip RK3568 has two USB XHCI controllers. The USB 2.0 signals are connected to a PHY providing one host-only port and one OTG port. The USB 3.0 signals are connected to two USB3.0/PCIE/SATA combo PHY. The ODROID M1 has 2 type A USB 3.0 connectors, with the USB 3.0 signals connected to the two combo PHYs. For the USB 2.0 signals, one connector is connected to the host-only PHY and uses the same power switch as the USB 2.0 ports. The other connector has its own power switch and is connected to the OTG PHY, which is also connected to a device only micro-USB connector. The purpose of this micro-USB connector is for firmware update using the Rockusb vendor specific USB class. Therefore it does not make sense to enable this port on Linux, and the PHY is forced to host mode.
