This message (from the core hub driver) looks important: 2016-11-06_17:33:29.19077 [ 7.510995] usb usb3-port1: connect-debounce failed The device tree source for Exynos 5422 was changed between 4.7 and 4.8 so some of the USB definitions could be shared with the 5410 (commit cb0896562228703209644e92926ed445150cc594).
