### 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

### DESCRIPTION

The u3g driver provides support for the multiple USB-to-serial interfaces exposed by many 3G USB/PC Card 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:

- Huawei E220 (E270?)
- Huawei Mobile
- Novatel MC950D
- Option Globetrotter 3G
- Option Globetrotter 3G Fusion (only 3G part, not WLAN)
- Option Globetrotter 3G Fusion Quad (only 3G part, not WLAN)
- Option Globetrotter 3G Quad
- Vodafone Mobile Connect Card 3G

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).
