ZWO ASI678MC - Resets

[danteffm]

Hi Aaron,

I'm just debugging my indi-allsky using a Raspberry Pi 5 + the ZWO ASI678MC.
Even when using an external and powered USB hub, I get lots of these errors when checking the USB status with dmesg -T | grep -i usb:

usb 1-1: reset high-speed USB device number 2 using xhci-hcd

vcgencmd get_throttled says throttled=0x0

Im already using bandwith=40 via config but this didn't help.
Any ideas what I also could do?

As indi-allsky sometimes stops (like once every 2-3 weeks) with error "Exposure State=ALERT" in the logs, I built a small watchdog which restarts the indi service automatically when there are no new pictures in the indi-allsky folder. So far, this works perfectly. Still I would like to find out how to fix the resets...

Cheers
Stefan

are you plugged into USB3 or USB2 port? I had similar problems with 676mc, switched to USB2 and they cleared up

These messages are normal and are a standard behavior of the camera driver.

The English is a bit broken, but this is from that post:

For the reset, now I am sure there is a reset, and I checked our program again,
find it this time. This reset is used to resolve internal device exceptions. For example,
the last time a unknown problem occurred, the device was not released, and the
next time you use it again, the device will be busy. With this function reset, the
device can be released, ensuring the next normal transmission. I am sure the reset
you find in the log is this. For this reset, we just reset our device. It will not affect
other devices.
