U3G(4)		       FreeBSD Kernel Interfaces Manual			U3G(4)

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:

     o	 Option	GT 3G Fusion, GT Fusion	Quad, etc. (only 3G part, not WLAN)
     o	 Option	GT 3G, GT 3G Quad, etc.
     o	 Vodafone Mobile Connect Card 3G
     o	 Vodafone Mobile Broadband K3772-Z
     o	 Qualcomm Inc. CDMA MSM
     o	 QUECTEL EC25, EM05, EM12-G.
     o	 Huawei	B190, E180v, E220 ('<Huawei Mobile>')
     o	 Novatel U740, MC950D, X950D, etc.
     o	 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 de-
     vice starts up in disk mode (TruInstall, ZeroCD, etc.) and	requires addi-
     tional 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 de-
			vices

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

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 un-
     less the driver is	either built into the kernel or	loaded before the de-
     vice is connected.
