If I use the libusb1 backend, then everything is fine. mymacmini:test xiaofanc$ cat test_libusb1.py #!/usr/bin/env python # import usb import usb.backend.libusb1 for d in usb.core.find(find_all=True,backend=usb.backend.libusb1.get_backend()): print type(d) dev = d._ctx.dev print type(dev) mymacmini:test xiaofanc$ python test_libusb1.py [timestamp] [threadID] facility
