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:

     ·   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
     ·   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, 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 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(5) and usb_quirk(4).
