When you say you have the latest app and firmware, is that the latest v1 or the new v2?

    Could you submi the log in the ASIAIR APP when appear this problem? (About -> feedback/bug report)
    Please also try different cables, and ports. thanks

          @Tech@ZWO#61200 I should have clear enough skies tomorrow night to do this.

          OK, so it is a problem with the new version. Hopefully they included the driver updates for the new cameras in that update.

              Hopefully they get to the bottom of this quickly. I just had it happen again (it's a constant headache during live stacking). I did upload the logs.

              Tech@ZWO "Exposure Failure" occurs very often with my ASI585MC. I just uploaded the logs. It's impossible for me to use my equipment until this is resolved... thanks!

                johnpd Hopefully they get to the bottom of this quickly. I can't get anything done until it's resolved.

                  A mi también me pasa, no puedo hacer exposiciónes de más de 0.5 segundos, me dice que encienda el cooler🤷‍♂️pero cual, esta cámara no tiene refrigeración

                    This is the same problem I was having with my new ASI662 before I updated to the latest v1. It sure appears that they did not include the updated drivers for the new 2022 cameras in v2. ASIAIR seems to recognize that there is a ZWO camera present, but it is confused as to what camera it is and what are its characteristics.

                        johnpd I have to believe if that was the case these forums would be full of complaints. There has to be a bunch of us out here using the new cameras with ASiair v2.. Anyhow, I’m watching it in the bug tracker now. I got my equipment out again last night and the problem is so random… Sometimes it will happen on the third sub, and sometimes on the 23rd. Grrr…

                            Regarding Jose's issue which was the same issue I had a while back, is there a log created when all you are doing is Preview Mode? I see logs on my system for Autorun and Guiding, but that is all.

                            Tech@ZWO It doesn't look like I'll have clear weather until Wednesday night, but I'll submit again ASAP. This happens each time with longer subs.

                              I submitted another bug report an hour or two ago... I wasn't able to use the PC, only the ASIair Plus again, as the clouds rolled in. I did the best I could with a very small hole in the weather. The error came on only the 7th live stacked frame shooting 30 second subs. This problem makes it impossible to use my new ZWO equipment, so I'm hoping for a quick resolution. Thanks for your attention to this!

                                tbhausen Did you test it with different USB cables and USB ports?
                                Can't locate where is the problem yet, we need more tests to rule out the problem first. thanks.

                                    Tech@ZWO thank you for your reply. I have new laboratory-grade cables arriving today so if the weather cooperates I will try again.

                                      Well... I never would have believed this, but no problems last night with new cable to ASI585MC, so I'm cautiously optimistic the problem is solved (I took up to 60 subs). For anyone else having problems with any camera, I'd be suspicious of the flat USB cables supplied by ZWO.

                                      Note: I got my new cables from usbfirewire.com (they have shortys and you can also specify the angle of the plug(s)).

                                      2 months later

                                      I am also having multiple Exposure failures with my ASI585MC. I have tried the two USB cables I have ( from ASI ) and plugged them both into the USB2 and USB3 ports. Still receive constant exposure failure. All of my issues are the same as tbhausen's. I have the latest ASIAir Plus with the V2 firmware. I believe that ZWO may have a cable problem.

                                        Never, ever use the data cables that come with your camera from ZWO. Go shop (Mouser, DigiKey, Amazon, or directly for companies that sources USB cables) for a cable that is spec'ed to be shielded, and have a length that is as short as can be, and still be able to reach from your computer to the camera.

                                        This may or may not completely solve the problem of your camera's USB port, but at least it should minimize the problem, and might make the interface start to work.

                                        Also, with your camera, you probably won't benefit from the speed from a USB 3 cable. Try a USB 2 cable (you can tell the difference from the shape of the Type-B connector -- USB 3 has that extra hump). Both ends of the USB cable will revert to using USB 2.0 protocol automatically (USB 3 is spec'ed to do that), and USB 2.0 is less demanding (both circuit design and PCB layout wise). That might also make your camera become usable.
