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"

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	 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
     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).

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.
