            Bug ID: 210830
           Summary: iPhone 5S not working with if_ipheth network driver
                    without changing setting config index to 3
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: usb
          Assignee: freebsd-usb at FreeBSD.org
          Reporter: woodsb02 at freebsd.org

On FreeBSD 11-current r302246 I was only able to get the ue0 network device to
show up after the ipheth(4) driver was loaded if I run:
# usbconfig -d X.Y set_config 3

 (where X and Y are the ugen values shown in dmesg when connected to USB)


Details of the configuration descriptors are shown below:
# usbconfig -u X -a Y dump_curr_config_desc
ugen0.4: <iPhone Apple Inc.> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
(500mA)
