Hello, I just tried to use the official master branch of libusbx on Mac OS X and I get a crash with the listdevs example:

I then tried https://github.com/jwrdegoede/libusbx/tree/darwin-integration but have the same bug (crash). I also tried https://github.com/hjelmn/libusbx/tree/darwin-integration but compilation fails with: make[2]: *** No rule to make target `os/poll_posix.c', needed by `libusb_1_0_la-poll_posix.lo'. Stop. The file os/poll_posix.c is not present in the repository. Where am I supposed to find the official/supported Mac OS X version of libusbx?
