Nothing. I suspected that maybe update to libASICamera2.so made this. But when I replaced it with 1.25 and 1.21 and it still bug out. Also when I connected camera to USB2.0 port it was working fine when plug back to USB3 it usually manage to do few exposures and then start failing. First instance was 1-2 months ago when my ASI1600 sometimes started to fail exposure. Usually it was working fine until switched from long 300s exposures to short 1s because refocusing or realign. These short ones then failed.

Then like two weeks ago my 485MC started to failing to get exposure sometime. Now it is failing all the time. But this gave me opportunity to debug this issue because I suspect that it is probably some timing race condition or something.

I created pull request. github.com/indilib/indi-3rdparty/pull/898
