This error is typically encountered with Allwinner SOCs when: CONFIG_CMD_USB_MASS_STORAGE=y but CONFIG_USB_ETHER is not set. Enabling CONFIG_USB_ETHER=y workarounded the issue for me, as reported also elsewhere: http://patchwork.ozlabs.org/project/uboot/patch/caexmxltm9bhx7aaub+mazgbdw2ccsoo3ne6ep7dbm8mmrya...@mail.gmail.com/#1976362 http://linux-sunxi.org/U-Boot/USB_Mass_Storage#Prerequisites Regards, Diego Rondini
