I just inherited a Logitech Quickcam Fusion, but where the heck are the drivers? I took a look at the Logitech site... and asked the same question. (Sidenote: Logitech, you need to get your act together. Where are your Linux drivers?).

Logitec Fusion Needless to say Ekiga could not use the cam. After much hair pulling, nashing of teeth and grumbling, I was able to Google enough information to put a solution together. If someone is looking for a solution on Feisty, read on...

First, I needed to install the linux headers for my kernel (so I could properly compile the drivers). To compile, I needed tools (GCC, etc.):
(Unplug the cam!!)

sudo apt-get install build-essential

sudo apt-get install linux-headers-386

* If you use i686 the make sure your command is: sudo apt-get install linux-headers-686 instead

To get a driver go here: http://svn.berlios.de/svnroot/repos/linux-uvc/linux-uvc/trunk/ and save each file to your sources folder. (Mine is .../root/sources/linux-uvc). The following should be saved:

Makefile
dynctrl.txt
svn-version.sh
uvc_compat.h
uvc_ctrl.c
uvc_driver.c
uvc_isight.c
uvc_queue.c
uvc_status.c
uvc_v4l2.c
uvc_video.c
uvcvideo.h

** I don't know what the rules are about distribution, but if they disappear or someone cannot get them, just say so in the comments section and I will have them.
Now that I had the drivers, run the following command in the same directory you saved them to:

sudo make && sudo make install

This installs those drivers and you can type "dmesg" in the same terminal (after plugging in the cam) to see the "xxxx class device" message. That means the drivers work.

I started Ekiga, but no-go... no video...

So:

sudo modprobe uvcvideo

Seems the problem was with Ekiga preferences? I tried Tried v4l2 on the video devices, and the set the 'USB video class device' to auto
(I'm going from memory in this last part as I didn't write it down... but I'm sure I saw that in a post in one of the links below). Either way... Wheeee!!! It works!

Only in Ekiga.

I don't remember every single page I looked at, but most of them are here. There is no way I could have figured all this out myself, so big kudos to all the contributors on those sites!:

Update: If you're looking for more information, I've found another resource that, among other things, has:

"...a script to install your webcam on ubuntu. The author has now one application for all the scripts. It does detect which driver is needed and installs the correct driver..."

You can find this (script) via http://ralph.n3rds.net/index.php?/archives/128-ubuntu-webcam.html

Additionally, there's information about Logitech QuickCam Express Plus and Ubuntu community webcam help.

If you like this post, why not share it?

I forgot to mention, the “Makefile” kept saving with a .htm extension. Just rename it without the extension!

To anyone who reads this..

You don’t have to manually copy the stuff from the http://svn.berlios.de/ url.. It’s a svn url which means it’s actually a lot easier to get the files. Here’s what you do:
(Subversion is a program that lets developers make it easy for people to access the source code, and if they want to, edit it!)

First, install the subversion client, don’t worry, it’s small!
$ sudo apt-get install subversion

Then, go to the folder you want to put the files in, and run:
$ svn co http://svn.berlios.de/svnroot/.....uvc/trunk/

This will download all the files automagically! Generally this is how you download any files from “http://svn…” URLs in general!

Also, it is both unnecessary and moreover, UNSAFE to run:
$ sudo make

You only have to run
$ make

But you DO have to run
$ sudo make install
because usually this is putting stuff in system-critical spots!

great, I can build and load the module with Kubuntu 8.04 also!

I do not know if the webcam actually works because I am using a virtual machine, so I cannot attach a webcam.

What is the device file that should exist after loading the module?

Again thanks for this tutorial!
