So to put some closure on this, owfs never worked reliably on my borderline bus when using the serial interface (it worked on the USB one for some reason). At least one of my devices would drop off the bus and sometimes some devices would not show up in /owfs via READDIR, but they were available via stat/open.
In the end, my problem was solved by adding a hub and just splitting the bus in smaller pieces, taking away whatever borderline case owfs wasn't happy with. Hope this helps someone.
