U3G(4)			 BSD 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 u3g
	   device ucom

     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	 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, pppd, 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 switch-
     ing 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.
