.Dd October 7, 2008 .Dt U3G 4 .Os .Sh NAME .Nm u3g .Nd USB support for 3G datacards .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device u3g" .Cd "device ucom" .Ed

p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent u3g_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides support for the multiple USB-to-serial interfaces exposed by many 3G usb/pccard modems.

p The device is accessed through the .Xr ucom 4 driver which makes it behave like a .Xr tty 4 . .Sh HARDWARE The .Nm driver supports the following adapters:

p l -bullet -compact t Option Globetrotter 3G Fusion (only 3G part, not WLAN) t Option Globetrotter 3G Fusion Quad (only 3G part, not WLAN) t Option Globetrotter 3G Quad t Option Globetrotter 3G t Vodafone Mobile Connect Card 3G t Qualcomm Inc. CDMA MSM t Huawei E220 (E270?) t Huawei Mobile t Novatal MC950D t Sierra cards .El (See /sys/dev/u3g.c for the complete list of supported cards for each vendor mentioned above).

p 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 (diagnostic port, SIM toolkit port)

p In some of these devices a mass storage device supported by the .Xr umass 4 driver is present which contains Windows and Mac OSX drivers. This device is hidden, unless the machine was booted in verbose (see .Xr boot 8 ). .Sh SEE ALSO .Xr tty 4 , .Xr ucom 4 , .Xr usb 4 , .Sh HISTORY The .Nm driver appeared in .Fx 8.0 , is based on the uark driver, and written by .An Andrea Guzzo Aq aguzzo@anywi.com in September 2008. .Sh AUTHORS The .Nm driver was written by .An Andrea Guzzo Aq aguzzo@anywi.com and .An Nick Hibma Aq n_hibma@freebsd.org .
