Purpose
Get external USB 3G HSDPA GPRS Modems to work with the Nokia N800 (or newer).
Steps
- Enable USB host mode.
- get a powered USB hub.
- connect your Nokia N8x0 to the USB hub's uplink.
- connect your USB Modem to one of the USB hub's normal ports.
- switch your Nokia N8x0 to USB host mode ("echo host > /sys/devices/platform/musb_hdrc/mode").
- 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, or check HSO in the meantime) for the Nokia N800.
- compile the "rezero" Option mode switch application (Rezero).
- run the Option mode switch application: "./rezero /dev/sg0".
- load the "HSO" kernel module: "insmod hso.ko".
- edit the "connect.sh" script (from HSO) to actually do the changes in the routing table.
- run the "connect.sh" script: "./connect.sh up".
- enjoy.
= Unused
- Alternative (generic?) mode switch program http://www.draisberghof.de/usb_modeswitch/
TODO
- make a ready-to-use Debian package.
