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).  This obviously shouldn't
have a functional difference to the 5422 but maybe it did?

Nothing is ever a complete failure; it can always serve as a bad
example.
