I think I may be getting to the bottom of this, there are two very similar cameras:

The ZWO ASI 120MM USB 2.0. This is a large diameter short camera with a T mount. It doesn't work although it might be persuaded to do so by installing different firmware.

The ZWO ASI 120MM MINI USB 2.0. Ths is an eyepiece sized longer camera, it has a C mount. This does work with the RasPi and ZWO bundle it with their ASIAir version.

The one I'm thinking of getting is the second, the MINI version. The ZWO forum and their support is pretty unequivocal that the 120mm mini works and the 120mm doesn't, at least with ASIAir.

Has anyone used the ASI120MM MINI with vanilla INDI rather than ASIAir?

Yop...sadly, it happens to me.... Grrrr

Ok, I confirm :
No hub and nothing else. I'm testing the camera on RPi3B+ alone by day (right now).
Bandwidth is on 40, Depth on 8bit.

And it doesn't work.

I allready flash the firmware but how can I be sure that it is the good one ?
I tried many parameters : restrict to 640x480, in strealming AND picture controls. I move bandwidht too but go back to 40 and even tried 16bit mode ;-)

Here is cpature of my ekos sreen with the puzzle...I have an average of 1/4 images like this.

I had an ASI120MC (USB2 version) as well and flashed it but never got it to work on Linux. Others on this forum have flashed it successfully. I guess your mileage may vary.

However, there is a third version: the ASI120MC-S (USB3). This one does work on Linux. I can confirm this because I have two and I use them all the time.

To my best of knowledge the ASI120MC MINI works on Linux but I am not 100% sure.

By the way, apart from the color version (MC) there also is a black and white version (MM) and all that I wrote applies to that as well, apart from the fact that I own or have owned one.

There is no such camera as the 120mc mini, they only make a mono version of this mini camera.. :)

And how about Bin 2x2? Did you try it? This reduces the image size and it should at least solve the "puzzle".
I always use mine at 2x2. Also 0.02s exposure is too fast for that camera in picture mode. The minimum
safest exposure I tested was 0.5s. Anything faster than this gives that puzzle. It's too fast for USB2.

Yes I tried binning too. But this is a software binning and I 'm not sure it is done in the camera before it send images via USB.

Well, I bought an ASI 120MM Mini and it works with the RasPi.

I had to rebuild the driver from the sources but I guess that's because I've been rebuilding Indilib and needed to build a compatible version of the camera driver.

I now I said you did not have the need to recompile the driver but as last resource, I would recompile it from the sources just to be sure.
Sometimes in the process of compiling some drivers on the ppa repository get screwed. It's not the first time it happens to me.
And recompiling solves the problem. Are you using the latest KStars / INDI drivers?

Give it a try.

Piling on!
I was looking for unrelated info and found this:
indilib.org/forum/ccds-dslrs/4878-qhy-5l...erry-pi-2.html#36864
The ASI cameras not liking external hubs is certainly not helping the situation.

I also remembered having not enough supply input current to the rpi3 main supply causing troubles. If you are using a wall wart, make sure it's not close to limits. Rpi instructions 2A but a 4A supply is better.

I'm not sure if this is a response to what I posted but what happened was that the ASI camera continued to work after recompiling and I was able to get the internal guider working. However the ATIK 383L+ driver wouldn't so no images.

I tried apt-get install indi-atik and that produced another error that was similar to the one the ASI driver produced. They both seem to be reporting an error referencing what looks like a mangled function name. So I tried the same fix, recompile from sources, and it worked. Now I can connect to both the main and guide cameras.
I've now got a system that works, or appears to, and that's good enough for now, I will wait until it is broke before fixing it.

I'd like to move on, do less developing, and spend some time actually using this kit to collect images.

Ideally I'd have two SD cards, a working one and a developing one, maybe I'll do that one day.
