Qualcomm makes the GOBI devices, and gobi_loader port supports all the Qualcomm GOBI 1000 and 2000 devices with the MDM1000 and MDM2000 chipsets. And likely the 3000 as well, though that's not been tested on FreeBSD. Submitted by: zarychtam@plan-b.pwste.edu.pl Sponsored by: Netflix

.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:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device usb"
|
|
.Cd "device ucom"
|
|
.Cd "device u3g"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
u3g_load="YES"
|
|
.Ed
|
|
.Pp
|
|
If neither of the above is done, the driver will automatically be loaded
|
|
by devd(8) when the device is connected.
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the multiple USB-to-serial interfaces exposed by
|
|
many 3G USB/PCCard modems.
|
|
.Pp
|
|
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:

|
|
(See
|
|
.Pa /sys/dev/usb/serial/u3g.c
|
|
for the complete list of supported cards for each vendor
|
|
mentioned above.)
|
|
.Pp
|
|
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).
|
|
.Pp
|
|
In some of these devices a mass storage device supported by the
|
|
.Xr 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.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver appeared in
|
|
.Fx 7.2 ,
|
|
is based on the
|
|
.Xr uark 4
|
|
driver, and written by
|
|
.An Andrea Guzzo Aq Mt aguzzo@anywi.com
|
|
in September 2008.
|
|
.Sh AUTHORS
|

.An -nosplit
|
|
The
|
|
.Nm
|
|
driver was written by
|
|
.An Andrea Guzzo Aq Mt aguzzo@anywi.com
|
|
and
|
|
.An Nick Hibma Aq Mt n_hibma@FreeBSD.org .
|
|
Hardware for testing was provided by AnyWi Technologies, Leiden, NL.
|
|
.Sh BUGS
|
|
The automatic mode switch from disk mode to modem mode does not work unless
|
|
the driver is either built into the kernel or loaded before the device is
|
|
connected.
|
|
.Pp
|
|
The GOBI-based devices require the gobi loader available from the
|
|
.Pa sysutils/gobi_loader
|
|
port.
