NAME

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

SYNOPSIS

       usbmuxd [OPTIONS]

DESCRIPTION

       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.

OPTIONS

       -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.

AUTHOR

       The first usbmuxd daemon implementation was authored by Hector Martin.

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