I just posted about this, on the 2 page thread, about rock 64 strange thread .. had not gotten to this thread yet.
I am going to go copy/paste what i said there, here, and remove it from there

I had posted about this in a different thread, before I found this thread .. I edit most of what has already been reported, out if the thread .. but I wanted to mention this, which helps sometimes ...
I have researched this a lot ... I tried a wired keyboard and mouse. Then, I plugged in a powered USB 3.0 hub, which has led's that light up, when a port is receiving a signal. When the problem happens .. I see the USB port get a signal, during start=up. I type password, a couple of seconds later, the USB port no longer receives a signal.
If the system is not shut down correctly, that greatly increases the chance of this happening. In that case, many times, the problem can be resolved by ... when you get to the log in screen .. do NOT type in your password .. instead ( In Xenial mate) .. click the power button at top right of the screen, and do a proper shutdown. About 50% of the time, a power off, then on, after doing this, works.
When it doesn't work, 3 or 4 times .. you might as well give up, and re-burn a new image and start over.
It is interesting that , there are occasions where I can run for a few days, with no problem .. boots up fine. Also never have a problem, before the log in screen, only after.
