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

       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, 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).
