Good morning, I bought a webcam called XSwebcam of TravelPAC. This webcam didn't worked. Do not worry, I have not directly posted a message to this mailing list. In fact, In fact, I took a look at http://doc.ubuntu-fr.org/webcam. In addition, I found a discussion in forum relative to this my webcam, titled: Problème de Webcam, logiciel EasyCam (Nouveau Topic)<http://forum.ubuntu-fr.org/viewtopic.php?pid=3153965> [unfortunately in french] and it was too long to follow (13 pages). So, let me to explain my problem: *My distribution:* Ubuntu 10.10 The name of my webcam given by that command *lsusb:* *Bus 001 Device 002: ID 0ac8:0332 Z-Star Microelectronics Corp.*
According to the documentation of Ubuntu, I should begin by testing the command *gstreamer-properties*.The result is as follows: The video entry is: * *modul (in french, it's greffon) *: Video for linux 2 (v4l2) ** peripheral*: Vega USB 2.0 Camera * *pipeline*: v4l2src device=/dev/video0" By clicking on the test button, *Nothing happens! No window has been opened and no video has been displayed.* The next step according to the ubuntu documentation is trying *cheese*. It has been installed successfully and cheese displayed just a black image continuously! Cheese returned 0 error message. The next step according to the ubuntu documentation is trying *camorama. *Things do not go well. camorama is blocked while adjusting the window siwe. camorama can be closed only by forcing it. The next step according to the ubuntu documentation is trying *guvcviewer*. It is well installed, 0 error message, black image displayed continuously. At this step, the ubuntu forum asked me try these commands: amine@amine-laptop:~$ dmesg | tail -20 [ 92.456297] Skipping EDID probe due to cached edid [ 92.944226] Skipping EDID probe due to cached edid [ 94.844249] Skipping EDID probe due to cached edid [ 99.640261] Skipping EDID probe due to cached edid [ 131.992815] synaptics: using relaxed packet validation [ 136.435435] lib80211_crypt: registered algorithm 'CCMP' [ 136.549907] padlock: VIA PadLock not detected.

The Ubuntu forum concluded that it could be possibly a driver bug. That's why I sent this message to this mailing list. Is there Any idea for solving this problem? Thanks you. --- Amine JALLOULI
