Well, that turned out okay after all. I dropped the hub and connected directly to the mount and ASI1600 using that latter as the hub for the filter wheel and guider. I did continue to get USB resets, as you said, on every exposure, but nothing every locked up or failed and I wasn't forced to power cycle or physically reconnect anything.
so I guess I'll need a new hub it I want to move further away from my mount.

I have to say that this still feels. wrong. It sounds like either there's an issue with the ZWO driver or the API isn't being used correctly because I can't see how normal, correct use should result in a device reset on every exposure :-/
