This is great. In the best of all worlds, your work will fix the libusb driver or OS implementation and we won't need special case code in OWFS. (If we do, that's fine, too.)
As for the binding, in module/owlib/src/c/ow_net.c routine ServerAddr uses getaddrinfo() with a hint of hint.ai_family=AF_UNSPEC seems to bind to IP6. The man page of getaddrinfo seems to suggest adding: hint.ai_flags = AI_PASSIVE | AI_ADDRCONFIG but you may want to check the freebsd documentation. I'm at a bit of a loss concerning the seg fault. It is possible that the thread handling is slightly different and the signals for closing threads isn't happy. Probably a lower priority issue.
