       usbmuxd  -  Expose  a  socket  to multiplex connections from and to iOS


       usbmuxd [OPTIONS]


       usbmuxd stands for "USB multiplexing daemon". This daemon is in  charge
       of  multiplexing  connections  over  USB to an iOS device. To users, it
       means you can sync your music, contacts,  photos,  etc.  over  USB.  To
       developers,  it means you can connect to any listening localhost socket
       on the device. usbmuxd is not used for tethering  data  transfer  which
       uses  a  dedicated  USB interface as a virtual network device. Multiple
       connections to different TCP ports can happen in parallel. The  higher-
       level layers are handled by libimobiledevice.

       When  usbmuxd  is  running (normally started, or stopped as a result of
       "udev" auto-insertion messages or by  systemd)  it  provides  a  socket
       interface  in "/var/run/usbmuxd" that is designed to be compatible with
       the socket interface that is provided on Mac OS X.

       You should also create a "usbmux" user that has access to  USB  devices
       on  your system. Alternatively, you can pass a different username using
       the -U argument.

       Due to iOS 7 the daemon now  also  manages  pairing  records  with  iOS
       devices    and    the    host   in   "/var/lib/lockdown"   (Linux)   or
       "/var/db/lockdown" (Mac OS X).  Ensure proper permissions are setup for
       the daemon to access the directory.


       -U, --user USER
              Change to this user after startup (needs USB privileges).

       -f, --foreground
              Do not daemonize (implies one -v).

       -n, --disable-hotplug
              Disables  automatic  discovery  of  devices on hotplug. Starting
              another instance will trigger discovery instead.

       -z, --enable-exit
              Enable  "--exit"  request  from   other   instances   and   exit
              automatically if no device is attached.

       -u, --udev
              Run in udev operation mode (implies -n and -z).

       -s, --systemd
              Run in systemd operation mode (implies -z and -f).

       -x, --exit
              Notify  a  running  instance  to  exit  if  there are no devices
              connected (sends SIGUSR1 to running instance) and exit.

       -X, --force-exit
              Notify a running instance  to  exit  even  if  there  are  still
              devices connected (always works) and exit.

       -v, --verbose
              be verbose (use twice or more to increase verbose level).

       -V, --version
              print version information and exit.

       -h, --help
              prints usage information.


       The first usbmuxd daemon implementation was authored by Hector Martin.

       Now mainly developed by Nikias Bassen, Martin Szulecki and contributors
       (see AUTHORS file).
