When USB does not work it's most likely that the usbmisc unit is not
properly configured. Have a look at mx25_initialize_usb_hw(). If you
previously loaded barebox with imx-usb-loader then you could try skipping
the initialization in mx25_initialize_usb_hw() completely.
I've seldomly seen that the actual EHCI driver or USB core is the
problem when no device is detected.
