Dspital has this ever been sorted out?
I don't think so. I suspect that ZWO has focused their people to other bigger emergencies that affect their bottom line more.
It is probably time that you move on to something other than an ASIAIR too. There are many other good solutions out there to control your astrophotography instruments, created by people who actually understand what they are doing.
You can probably use a USB Protocol analyzer in between the ASIAIR and your mount to see what data it is trying to pass. I had written one such program many years ago for MacOS X:

Today, you can also use WireShark to sniff the USB ports, and see traffic that is passing between USB devices.
The problem is that even if you spoonfeed the bug fix to ZWO, they will still not fix it. Ask me how I know.
