WUSB54GC

Overview

Here you can find the following files for Ubuntu Dapper 6.06 LTS:

ralink-rt73_1.0.3.6_all.deb (Firmware and udev scripts)
ralink-rt73-source_1.0.3.6_all.deb (module source package for module-assistant)

Compile

If you want to build a module package for your locally installed kernel follow these steps:

install the kernel headers for your kernel:

	    sudo apt-get install linux-headers-$(uname -r)

install module-assistant:

	    sudo apt-get install module-assistant

install the module source package:

	    sudo dpkg -i /path/to/ralink-rt73-source_1.0.3.6_all.deb

run module-assistant to build the customized kernel module package:

	    cd /tmp
	    mkdir module
	    m-a -l $(uname -r) -t -u module build  ralink-rt73

install both the module and the firmware package:
```
	    sudo dpkg -i /path/to/ralink-rt73_1.0.3.6_all.deb
	    sudo dpkg -i /tmp/module/ralink-rt73-$(uname -r)_1.0.3.6+<KERNEL-PACKAGE-RELEASE>_i386.deb
	  
```
where KERNEL-PACKAGE-RELEASE is the actual Dapper kernel version name (eg 2.6.15-27.48). Just have a look into /tmp/module to get the name of the deb package you have just built.
Keep your deb file and clean up the temporary directory /tmp/module if no longer needed.

In case you intend to build the module for another than your installed kernel replace the $(uname -r) snippets above with the desired kernel version (e.g. 2.6.15-27-k7).

Usage

If you now plug your WUSB54GC in, you will get a rausb0 device which you may configure with iwconfig and ifconfig.

Please note that you dont need any alias entries in /etc/modprobe.conf with this package, automatic module loading is provided through the udev script /etc/udev/rules.d/50-ralink-rt73.rules contained in ralink-rt73_1.0.3.6_all.deb.

Details

If you are interested in rebuilding the module source package get

and extract it with

	dpkg-source -x ralink-rt73_1.0.3.6.dsc

You can then examine its contents in the subdirectory ralink-rt73-1.0.3.6. It contains the upstream source, two patches (one adds the device ID of the LinkSys WUSB24GC, the other makes the Makefiles usable for m-a) and the Debian specific build stuff.

Rebuilding can be done via

	debuild

in the ralink-rt73-1.0.3.6 directory, provided you have installed the debuild package and co (e.g. fakeroot).

This may be necessary if a new upstream version of the driver becomes available, the only thing to do is then to download it into the upstream directory and change the variable UPSTREAM in debian/rules to the new upstream package name.

Source

This is a Debian style repackaging of the OpenSource RT73 driver available at
http://www.ralinktech.com.tw/data/RT73_Linux_STA_Drv1.0.3.6.tar.gz

The Debian specific stuff follows ideas stolen from the rt2500 Debian package by Aurelien Jarno (aurel32 at debian.org)

Other Modifications

If you want to use WPA for your RT73 based card you need a modified wpasupplicant package which includes the ralink driver provided in the RT73_Linux_STA_Drv1.0.3.6.tar.gz package. You can get it from our local repository at http://ubuntu.uni-klu.ac.at in compiled or in source form.
The difference between the Dapper wpasupplicant (version 0.5.5) and the modified one consists in adding the following patch: debian/patches/22_add_ralink.dpatch

Furtermore, if you want to use NetworkManager, you need to patch it to use the above mentioned ralink wpa_driver, modified network-manager packages are also available at http://ubuntu.uni-klu.ac.at.
Again it is only a small diff to apply to the network-manager package (version 0.6.2): Add debian/patches/99-ralink.patch
