.Pp
The following example shows how to manually configure network access on a
device that is not automatically recognized.
.Pp
First, load the driver and find out the unit and the address of the USB
Apple
device:
.Bd -literal -offset 2n
.Li # Ic kldload ipheth
.Li # Ic usbconfig | grep Apple
ugen0.2: <Apple Inc. iPhone> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)
.Ed
.Pp
In this example, the unit and the address of the device is 0.2
.Pq Dq Li ugen0.2 ,
and its configuration index is 0
.Pq Dq Li cfg=0 .
.Pp
Secondly, check what other configurations are available for the device:
.Bd -literal -offset 2n
.Li # Ic usbconfig 0.2 dump_all_config_desc | awk '/^ Conf/{print} /iConf/{print}'
Configuration index 0
iConfiguration = 0x0005 <PTP>
Configuration index 1
iConfiguration = 0x0006 <iPod USB Interface>
Configuration index 2
iConfiguration = 0x0007 <PTP + Apple Mobile Device>
Configuration index 3
iConfiguration = 0x0008 <PTP + Apple Mobile Device + Apple USB Ethernet>
.Ed
.Pp
In this example, there are 4 different configurations available.
The configuration with index 3 seems to be related to Ethernet.
It is time to configure the device:
.Bd -literal -offset 2n
.Li # Ic usbconfig 0.2 set_config 3
.Li # Ic usbconfig | grep 'Apple.*cfg=3'
ugen0.2: <Apple Inc. iPhone> at usbus0, cfg=3 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)
.Ed
.Pp
At this point the Apple device should ask whether the
.Fx
machine can be trusted
.Po Dq Mobile Data
has to be on
.Pc .
.Pp
A new
.Em ue
USB Ethernet interface should become available:
.Bd -literal -offset 2n
.Li # Ic dmesg | grep 'ue[0-9]'
ue0: <USB Ethernet> on ipheth0
ue0: bpf attached
ue0: Ethernet address: 4e:7c:5f:2c:5f:7a
.Ed
.Pp
At this point it might be necessary to run
.Xr usbmuxd 1
.Po available in
.Xr ports 7
at
.Pa comms/usbmuxd
.Pc :
.Bd -literal -offset 2n
.Li # Ic usbmuxd --enable-exit --foreground --user root --verbose
.Ed
.Pp
Now it is time to configure the network interface:
.Bd -literal -offset 2n
.Li # Ic sysrc ifconfig_ue0="SYNCDHCP"
ifconfig_ue0: -> SYNCDHCP
.Li # Ic service netif restart ue0
.Ed
.Pp
That is it.
The machine should now be connected to the network via USB tethering.
