I've never seen the problem on my Raspberry Pi 4. -- I have seen it on my rpi4

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.

I've traced it down a bit. It looks like it's happening in the asi binary driver when called from:

asi_base.cpp::workerExposure(){
...
ret = ASIStartExposure(mCameraInfo.CameraID, isDark);

It does not return an error, but as soon a the call finishes the dmesg error happens, so it seems to reset when inside of that ASI call.

much ado about nothing. This is NOT a problem, just the way it works. See last message in this (from SAM, ZWO) bbs.astronomy-imaging-camera.com/d/9937-...-reset-on-each-frame

When I still used to use Ekos, you saw that message every time (use dmesg to see it when capturing) with all of my cameras.

I have three ZWO cameras and all of them works correctly. This messages about USB reset in dmesg is indeed normal.

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.

"It's a feature, not a bug"!?
