NAME

       u3g — USB support for 3G datacards

SYNOPSIS

       To compile this driver into the kernel, place the following lines in your kernel configuration file:

             device usb
             device ucom
             device u3g

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             u3g_load="YES"

       If  neither  of  the above is done, the driver will automatically be loaded by devd(8) when the device is
       connected.

DESCRIPTION

       The u3g driver provides support for the multiple USB-to-serial interfaces exposed by many  3G  USB/PCCard
       modems.

       The device is accessed through the ucom(4) driver which makes it behave like a tty(4).

HARDWARE

       The u3g driver supports the following adapters:

       •   Option GT 3G Fusion, GT Fusion Quad, etc. (only 3G part, not WLAN)
       •   Option GT 3G, GT 3G Quad, etc.
       •   Vodafone Mobile Connect Card 3G
       •   Vodafone Mobile Broadband K3772-Z
       •   Qualcomm Inc. CDMA MSM
       •   Huawei B190, E180v, E220 ('<Huawei Mobile>')
       •   Novatel U740, MC950D, X950D, etc.
       •   Sierra MC875U, MC8775U, etc.

       (See /sys/dev/usb/serial/u3g.c for the complete list of supported cards for each vendor mentioned above.)

       The  supported  3G  cards  provide  the necessary modem port for ppp, or mpd connections as well as extra
       ports (depending on the specific device) to provide other functions (additional command port,  diagnostic
       port, SIM toolkit port).

       In some of these devices a mass storage device supported by the umass(4) driver is present which contains
       Windows  and Mac OS X drivers.  The device starts up in disk mode (TruInstall, ZeroCD, etc.) and requires
       additional commands to switch it to modem mode.  If your device is not  switching  automatically,  please
       try to add quirks.  See usbconfig(8) and usb_quirk(4).

FILES

       /dev/ttyU*.*       for callin ports
       /dev/ttyU*.*.init
       /dev/ttyU*.*.lock  corresponding callin initial-state and lock-state devices

       /dev/cuaU*.*       for callout ports
       /dev/cuaU*.*.init
       /dev/cuaU*.*.lock  corresponding callout initial-state and lock-state devices

EXAMPLES

       Connect to the Internet using the default configuration:

             ppp -background u3g

HISTORY

       The  u3g  driver  appeared  in  FreeBSD  7.2, is based on the uark(4) driver, and written by Andrea Guzzo
       <aguzzo@anywi.com> in September 2008.

AUTHORS

       The u3g driver was written by Andrea  Guzzo  <aguzzo@anywi.com>  and  Nick  Hibma  <n_hibma@FreeBSD.org>.
       Hardware for testing was provided by AnyWi Technologies, Leiden, NL.

BUGS

       The  automatic  mode  switch from disk mode to modem mode does not work unless the driver is either built
       into the kernel or loaded before the device is connected.
