I too use a NanoPC T4. I added a 500 gig solid state drive to it, which takes up no additional space in its tiny plastic case.
12v 2 amp. Comes with 16 gig eMMC and 4 gig ram, 5G wifi, USB 2 and 3, ethernet, dual camera interfaces etc, etc. I run Lubuntu 16.04 on it. It goes from cold power-on to fully booted and ready for my ipad or Macbook to connect to it in just six seconds.
I tried connecting ONLY the ASI1600MM to the NanoPC T4 and got the same problem.
Still works great when connecting to the USB2 ports, but fails after one or twi images when connected through the USB3 port,
I used the same cables to connect my MacBook Air - and it worked great, so the issue is not the camera or cables.
What OS are you using n you T4? I have Lubuntu 16.04.
I have never been able to get my ASI1600MM to work when connected via USB3.0 to my computers (I tried two).
They are running Ubuntu 16.04 and using the latest updates to INDI and EKOS.
It downloads the first or second image in a sequence, but then hangs when trying too get any more.
The strange thing is that when I connect with USB2 cables, all is fine (just at USB2 speeds). This after I power down the camera though.
The USB bandwidth is set at the lowest setting (40).
I attached the log file.

Fantastic! Thank's for setting me straight!
Thinking of getting a Celestron RASA 11, but am concerned that EKOS is not quite ready for the Celestron Electronic focuser.
How is the development coming along on this?
When I use the LEGACY version of the Polar Alignment routine, EKOS will start a photo capture without waiting for a delay after slewing. The result is blurred images that it then tries to identify with asymmetry. I set the delay time, and that works in regular alignment mode, but not in the Polar Alignment mode (the legacy version, I can't use the new version at the Equator).
I now have 3.1.1 on the Mac and Ubuntu. Both systems still cause my my guidestar to move in a non-random almost linear direction (-3,-3) when dithering. I have it set to dither 3 pixels every three frames. But when I look at my resulting imagines (I did 30 exposures last night) every dither was 3 pixels movement to the upper left. So the whole image was off center by 30 pixels in that straight direction (up and left). I have to aligned my exposures every 30 minutes or so just to keep my target centered. While those few pixels are not huge, after a 3 hour session it is, and objects on the left side of the frame are moved off the frame.
My NANO PC sets up a wifi network upon booting. It's crazy, as it has this network up and running in 6 seconds from power on.
The Starfi has a STAtion mode that creates it's own wifi network. INDI then connects to that.
(I will verify all the settings when I get home)
My Mac also connects to the same NanoPC wifi network to gain access to INDI, and the shared drive folder (SSD).
I am running Lubuntu.
The case is the clear plastic one (top and bottom only).
I tried the steel fully encased one, but it seemed to run very hot that way.
Interesting. I am using the same mount with Mac OSX 3.0 Kstars.
The mount moves correctly when tracking, slewing and guiding.
But I have found one other time it may be reversed, in the legacy Polar Alignment routine. In that tool, it directs me to adjust the mount in the opposite direction it should be .
Just a short chime, to say that I too use a new Macbook (Air) now to to connect to my astrorig. I was just connecting via VNC to the Linux box that was running INDI/Kstars, but lately its just been too buggy to be reliable.
So now I use the Mac to run the OSX version of KStars and connect to the same Linuxbox (NanoPC T4) and that works great! It's fast, and I solved the issue of download times by installing a 500GB Solid State Drive card onto the NanoPC and have EKOS save files to it instantly. Then I connect to the NanoPC via SMB and share that SSD on my Mac. I can then download files at a later time easily.
I connect the Macbook to the NanoPC via a local wifi network.
The NanoPC rides shotgun on my mount and all my equipment is plugged into the NanoPC which has both USB2 and USB ports. One 12V powercable leads to a saddle on the mount which uses a RigRunner powerstrip #405 to distribute power to the cameras, focuser, NanoPC, and dew heater.
The NanoPC (running INDI) connects to the iOptron CEM25P via iOptron's StarFi wi adapter. It's flawless.
PS: I too would love to see the GAIN and OFFSET settings right on the Capture screen, so they can be incorporated easily in an imaging session.
So when I go out in the field, here's what happens:
1. I setup the mount and attach the entire astrorig to it. I store my complete imaging rig all assembled in a Pelican case. I just take it out of the case, and attach it to the mount. No assembly required. This includes my WO STar71, ASI1600MM Pro, OAG with Lodestar X2, Filter wheel, dew heater with temp probe, NanoPC T4 (Lubuntu), and powerstrip.
2. I turn on the mount and wait for it to aquire it's GPS settings. While it is doing that, I adjust the balance of the imaging setup.
3. I turn on the NanoPC T4 and 6 seconds later it has connected to the Starfi (iOptron CEM25P) and is broadcasting it's own network.
4. I Open my MacBook, connect to the Nano's network, and start KSTARS.
5. Ready to roll! I do a polar alignment, and start my imaging session.
That whole setup from car to imaging takes about 30 minutes.
Maybe there is a way to resolve this already, but I have not seen it.
Problem. After many ditherings, the target can be quite a bit away from where it started.
Often, it's not a problem, as it's not off by much, and my target is centered anyway.
But occasionally, on very large subjects, I can find that dithering moves a critical star or object that was on the edge of the frame off the edge.
Solution: After a set amount of ditherings (user controlled), EKOS performs a re-alignment using the very first image in the session as the reference image.
Everything was working great on my Mac’s version of KStars and EKOS, until last night.
On application startup, KStars complains about INDI directory:
“Unable to find INDI Drivers directory: /usr/local/share/indi
Please make sure to set the correct path in KStars configuration”
And ideas of how to fix this?
