Revision as of 07:53, 21 April 2009

This guide covers using external USB 3G HSDPA GPRS modems with Maemo.

Steps

  • Enable USB host mode.
  • Get a powered USB hub.
  • Connect the hub to your tablet.
  • Connect your modem to the USB hub.
  • Compile a SCSI generic Linux kernel module (or download a binary module from CDROM Kernel Modules).
  • Load the SCSI generic Linux kernel module. 
insmod sg.ko

Option HSDPA Modem

  • Compile the "HSO" Option Modem kernel module (Greg Kroah-Hartman is in the process of integrating the kernel module into the mainline kernel, but check HSO in the meantime or use this working directory which includes compiled modules).
  • Compile the Rezero Option mode switch application.
  • Run the Option mode switch application. 
./rezero /dev/sg0
  • Load the "HSO" kernel module. 
insmod hso.ko
  • Edit the <code>connect.sh script (from HSO) to actually do the changes in the routing table.
  • Run the connect.sh script. 
./connect.sh up
  • Enjoy!

TODO

  • Create a ready-to-use Debian package.
  • Use the udev script to automate the loading when the device is plugged (both for "rezero" and for "HSO").
