j'ai suivi ce wiki:
http://gentoo-wiki.com/HARDWARE_Dell_Inspiron_1520#Webcam
j'ai bien pris la version SVN et modifie le fichier
mais quand je modprobe uvcvideo, dmesg m'indique ceci:

uvcvideo: Found UVC 1.00 device Laptop Integrated Webcam (05a9:2640)

merci
RESOLU
elle marche en fait... il faut juste utiliser http://mxhaard.free.fr/download.html luvcview pour le tester

I have the same problem, but the webcam works with luvcview ( not with mplayer/gstreamer/...). I think it's because v4l2src and mplayer use read() and linux-uvc only support mmap() or something like that... EDIT:Work with ekiga!
