Hi Matthew,

It appears that setting CONFIG_MXC_USB_PORT to 0 then loads the OTG port on the i.MX53. The code appears to be in drivers/usb/host/ehci-mx5.c. The problem then is that the USB host port is then not usable since my i.MX53 board dedicates the OTG port to USB client functionality only.
Now I am trying to get both USB Host port 1 and USB OTG port 0 working at the same time. Does u-boot allow using multiple USB controller ports at the same time?
Yes, you can use both ports.
In order to do so, you need to pass #define CONFIG_USB_MAX_CONTROLLER_COUNT 2 in your config file.
