There are two ways to fix it: 1) dts|dtb , or script , to toggle the mux lines turning the regulators ON, or 2) mod the board so that the regulators are ON all the time !
The regulators are on the schematic on page 19; We'll do some testing and see if we can get a software fix; otherwise, we'll put up a board mod procedure.
I have an additional bit of information. If you open the 'PulseAudio Volume Control' window in Debian LXDE Build 20170809, this seems to immediately kill the USB ports. After getting the USB keyboard and mouse working, everything was good until I opened the PulseAudio Volume Control window. Then the keyboard and mouse were suddenly dead. This happened twice.
I assume this is related to the above issue regarding the gpio mux lines are left floating?

Same issue here.

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.

Anyone know where we are on this problem?
I am.. Hesitant to post about the rock 64, to other forums (like the RetroPie forums), untill we get a solution to this problem (because it is a major stumbling block.. At least for me).
I know there is a.. Apparent problem with ethernet drivers/ethernet chip.. But I am not experiencing that.. But I am experiencing the usb problem.
I am not.. Whining... complaining, just trying to figure out where we are with this.. Imho, major problem.

It will be fixed in software ... both Xalius and Ayufan haven't gotten their production boards (they are stuck somewhere) so can't fix it. Its a software fix, so dont worry.
RE: No USB Power after Login (ROCK64+Mate) - MarkHaysHarris777 - 08-23-2017
I am building the fix for this as we speak; it will be ready today.
Initially I'm going to provide two scripts -- 1) manual control, 2) automated control
The automated script will be a systemd service unit. Eventually we will provide a customized dts entry for device tree; since most users will just want the power ON and don't care; the systemd server unit will be for those who want control of the usb power line to be able to cycle power to usb devices (or other relays).
I will post here when complete; and I will post a special thread with the scripts -- further , I will push the items on github as PR for ayufan.

I think the kernel changes have already been done and just the images and sources need to be updated.
