Bisecting shows that this happened starting from commit 874dde80169e0a0c00020e2e0bbcd380c61097e3 ("dm: usb: exynos: Use driver model for USB"): http://git.denx.de/?p=u-boot.git;a=commitdiff;h=874dde80169e0a0c00020e2e0bbcd380c61097e3 Below are the logs from the serial console. === works properly == U-Boot 2015.04-00271-g52e6935-dirty (Oct 20 2015 - 16:38:09) CPU: Exynos4412 at 1000MHz Model: Odroid based on Exynos4412 DRAM: 1 GiB Board PMIC init MMC: SAMSUNG SDHCI: 0, EXYNOS DWMMC: 1 Net: No ethernet found.
