Setting up BandLuxe C179 on Karmic

I've recently signed up with Singtel's mobile broadband, which uses a BandLuxe C179 HSDPA USB modem. Hers's how I set it up on Ubuntu 9.10:

• Download Linux driver from http://www.bandrich.com. The file name of the download "C270-Eee-PC_Linux-driver.zip" suggests it's intended for C270.
• The product id in bandluxe.fdi is wrong, change it to:

  <match key="usb.vendor_id" int="0x1a8d">
  <match key="usb.product_id" int="0x1009">
  

• The kernel module option.ko that comes with the driver doesn't work with 2.6.31 kernel. And we don't need it anyway, so comment out its installation from eeepc3g.sh:

  #echo "Backup file option.ko"
  #cp -v ${MODDIR}/kernel/drivers/usb/serial/option.ko ./option-eeepc.ko
  #echo "Add support of Bandluxe Data Card"
  #cp -v option-bandluxe.ko ${MODDIR}/kernel/drivers/usb/serial/option.ko
  

• Install the driver:

  $ sudo ./eeepc3g.sh
  $ sudo modprobe option
  

• Plug in the modem.

  $ lsusb
  Bus 001 Device 003: ID 1a8d:1009
  ...
  

  So the modem has been detected. Before installing the driver, we only had 1a8d:1000, which is the USB storage device. We also have some new devices now:

  $ ls /dev/ttyUSB*
  /dev/ttyUSB0   /dev/ttyUSB1   /dev/ttyUSB2
  

• Update /etc/wvdial.conf:

  [Dialer Defaults]
  Modem = /dev/ttyUSB0
  Baud = 7200000
  Init1 = ATZ
  Init2 = ATQ0 V1 E1 S0=0 &C1 &D2
  Init3 =
  Area Code =
  Phone = *99#
  Username = ppp
  Password = ppp
  Ask Password = 0
  Dial Command = ATDT
  Stupid Mode = 1
  Compuserve = 0
  Force Address =
  Idle Seconds = 0
  DialMessage1 =
  DialMessage2 =
  ISDN = 0
  Auto DNS = 1
  

• Finally

  $ sudo wvdial
  ...
  $ ifconfig
  ...
  ppp0      Link encap:Point-to-Point Protocol
        inet addr:119.234.175.186  P-t-P:10.64.64.64  Mask:255.255.255.255
