As far as I understand the patches here https://github.com/libusb/libusb/issues/906 they are internal to libusb, so we would need to build a libusb for use with e.g., brew to build a macOS executable. Or wait for them to be finalised to get included in libusb and then included in brew and then .... Best, Howard
