ZWO Camera ASI 120MM Mini Mono with StellarMate? #44511
To my best of knowledge that firmware is for ASI120MM/MC and not for the mini since there is no downloadable firmware for the mini. This essentially is the compatibility firmware that you probably already applied. I did the same thing once and never got my ASI120MC to work properly as well so I replaced it with an ASI120MC-S (USB3 version) and that works like a charm.

A search on 'cypress chipsets usb' should throw it up. I always had difficulty finding it so when I had it working, I saved a copy.
I have only tested it on Ubuntu on a Dell laptop. The reason we needed it is that we didn't have a spare usb2 port. You can choose which zwo model you have on the command line when you update the firmware.

I’ve noticed that my firmware updated ASI120MC now works fine as a guide camera on my Kubuntu laptop and the raspberry pi 4 running raspbian buster, I’m using the internal guider, setup on the raspberry pi via Rob’s Astropi3 script. No broken frames or dropouts however, it will not stream video without the frames breaking up and it still won’t work correctly on a raspberry pi 3 or 3 B+ set up in the same way.

I also noticed that my ASI 120MM (USB2) is stable on my RPi4. But I have not had an opportunity to use it in a session yet.

I can confirm that the ASI120MM (USB2 version, updated firmware) works on the Pi4 under Manjaro Linux and KStars 3.3.6 as long as exposures are kept at >0.5s. At <0.5s frames are sometimes garbled, which is obviously not good for guiding.
And once the frames get garbled, it's only a matter of time until KStars crashes.
Within these limitations, the ASI120MM may still be useful for guiding, but not much else on Linux.
