I also had a lot of problems with the version that came with Indi 1.9.1.
I compiled the version of Azwing (github.com/azwing/indi), then just replaced indi_lx200generic in my existing installation (in /usr/bin/).
That works well.
I think it must be possible to also recompile version 1.9.0 and replace indi_lx200generic
I gave this a shot and the driver does appear to be more stable. It recognizes if i have a focuser or not on my OnStep controller. That is new. The older drivers just loaded all parts and did not check the OnStep controller if they existed.
I still do not have good communication with the OnStep controller. My first problem i encounter is it says it cannot get site info and it cannot write UTC offset.2021-09-12T13:08:17: [ERROR] Error setting site longitude coordinates
2021-09-12T13:08:17: [ERROR] Error setting UTC Offset.
If i request a 3star align it says error.

I am connecting to the web manager of OnStep and that website is running correctly. It is only my local wifi network.
I also see that the driver has a blank page on OnStep status.
