Logitech QuickCam Messenger

with 3 comments

I wanted to install my Logitech QuickCam Messenger on Ubuntu Gutsy. I read this, this and this.

From dmesg i was getting:
[ 147.544000] usb 2-1: new full speed USB device using uhci_hcd and address 2
[ 147.732000] usb 2-1: configuration #1 chosen from 1 choice
[ 148.120000] usbcore: registered new interface driver snd-usb-audio
and from lsusb i was getting:
Bus 001 Device 003: ID 046d:08f6 Logitech, Inc.

After sudo modprobe uvcvideo, dmesg gives me:
[ 292.880000] Linux video capture interface: v2.00
[ 292.924000] usbcore: registered new interface driver uvcvideo
[ 292.924000] USB Video Class driver (v0.1.0)

Easycam (lauchcam) just tells me:
Forum address : http://forum.ubuntu-fr.org/viewtopic.php?id=16670
Email address : jbtheou@gmail.com
Please forward me the following text to one of following addresses :
ID 046d:08f6 Logitech, Inc.

But after running it, ls /dev/video* now gives me:
lrwxrwxrwx 1 root 11 2008-01-27 16:01 /dev/video -> /dev/video0
crw-rw-rw- 1 root 81, 0 2008-01-27 16:01 /dev/video0
crw-r–r– 1 root 81, 1 2008-01-27 16:01 /dev/video1

camorama is telling me it couldn’t connect to /dev/video0,
but camorama -d /dev/video1 doesn’t work either

I started exploring in /usr/share/EasyCam/Qcnews/qc-usb-messenger-0.9 and came across _README_MESSENGER which suggests
sudo modprobe videodev; sudo modprobe quickcam

  2. After reading GregKH’s book on kernel customization, I followed his instructions on finding the correct module from scratch. My cam is 046d:08f6. However the kernel drivers/ directory contains (under drivers/media/video/usbvideo) the driver quickcam_messenger.c, which only supports 046d:08f0. I did some hacking of the c code, made the module, installed and now it works!!!!

  3. the driver included in the linux kernel is an old one (05/08/2006 – Jaya Kumar). it still uses the V4L1 API.

    in the meantime I found this one: http://home.mag.cx/messenger/ by Christian Magnusson (mag@mag.cx), latest version qc-usb-messenger-1.7 (02/09/2007), which also supports 046d:08f6, even though it thinks it’s the Logitech Quickcam Messenger Plus…

    it seems to be connected to the guy doing the easycam & easycam2 utilities: http://blognux.free.fr/Drivers/qcnews/
