It performs a couple of libusb operations at that point:

  if (usb_set_configuration(udev, dev->config[0].bConfigurationValue))
    {
      fprintf(stderr,
              "%s: usbdev_open(): error setting configuration %d: %s\n",
              progname, dev->config[0].bConfigurationValue,
              usb_strerror());
      goto trynext;
    }

  usb_interface = dev->config[0].interface[0].altsetting[0].bInterfaceNumber;
  if (usb_claim_interface(udev, usb_interface))
    {
      fprintf(stderr,
              "%s: usbdev_open(): error claiming interface %d: %s\n",
              progname, usb_interface, usb_strerror());
      goto trynext;
    }

  fd->pfd = udev;
  return;
