CONFIG_MXC_USB_PORT was used to define which USB port was to be initialized. If CONFIG_USB_MAX_CONTROLLER_COUNT > 1, then the port specified by CONFIG_MXC_USB_PORT would be duplicated CONFIG_USB_MAX_CONTROLLER_COUNT times including duplicating all devices connected to the ports. None of the other USB ports would be available for use.
The fix is to remove all instances of CONFIG_MXC_USB_PORT from the imx53 ehci driver since it was only allowing the port specified by CONFIG_MXC_USB_PORT to be populated. Then use CONFIG_USB_MAX_CONTROLLER_COUNT to specifiy which USB ports
should be
enabled, starting with port 0. If port 1 is needed, then set CONFIG_USB_MAX_CONTROLLER_COUNT to 2 so 2 ports get populated
(port 0
and port 1) even though port 0 will not be used.
Configurations for all boards affected are updated.

Perhaps instead this should move to driver model - it supports EHCI. See tegra, exynos, sunxi and sandbox.
Wouldn't that require imx53 support for device trees? Currently I don't believe that is implemented yet.
