One more thing. I also see that error on my raspberry PI4. It doesn't seem to affect performance so bad that I can't use it, but it must be causing an issue.
Could you do me a favor and issue this command in the terminal while the camera is capturing?
dmesg -wH
It will show if a reset is happening.
I can confirm that I also see this on my raspberry pi 4 running astroberry or stellarmate. I can reproduce it on a variety of versions of indi and kstars
Indi: v1.9.5, v1.9.7, v1.9.5.8, master
kstars: stable-3.5.9, stable-3.6.1
It may be some sort of issue with my particular camera, or it may be happening to all zwo 1600's. I'm still able to use the camera, it just slows things down, and may cause other issues.

It doesn't seem to be happening with my zwo asi 178 for some reason.
I wouldn't call a usb reset normal, but it does appear that zwo is using a reset to get past some bugs in their cameras firmware. Looks like they are resetting with every capture. It happens inside of the ASIStartExposure call. It's seems to be done to work-around some bug.
The same happens with our ASI294MC: "usb 1-4.4.2.3: reset high-speed USB device number 12 using xhci_hcd" over and over, every time EKOS take a capture.
