I know I've seen a reference to this before somewhere, but I just cannot recall where, nor what the resolution was, and I can't find any meaningful search results. Does it ring a bell with anyone?
Not really ringing a bell, but you might try removing the files ~/.indi/ASI EFW_config.xml* (~ of whatever user runs the indiserver...) and/or purge the config of the wheel in the options tab...
