I do not see issues with older = S905 (WeTeK Play2) or newer S922X (Odroid N2+) devices running the same = kernel. There are no kernel splats or error messages but lsusb shows no output = and nothing works. Simple revert restores the previous good working = behaviour. dmesg with commit http://ix.io/3ZTv dmesg with revert http://ix.io/3ZTw I=E2=80=99m not a coder so will need to be fed instructions to assist = with debugging the issue further if you don't have access to an Amlogic S912 device. I = can share devices online for remote poking around if needed. Christian=
