In fact it is very simple to test USB on a 3.18 kernel with your hardware.

You only need a minimal dts file with the usb/serial nodes enabled.

Take a loot at arch/arm/boot/dts/imx51-babbage.dts for a reference.

I tested USB earlier today on this board with 3.18 and it worked fine.
You need this patch:
