Has anyone seen that > issue in 3.x kernels? 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: http://www.spinics.net/lists/arm-kernel/msg385739.html Regards, Fabio Estevam
