    If you would like assistance the following would help.

    1. Ask for assistance, just stating something isn't working is a very rude way to start a conversation because it sounds like you are expecting us to solve your problem with very little initiative or cooperation from you.
    2. Tell us what version of Ubuntu you are using
    3. Give us the device information about the non-working device (I am assuming it is a webcam) as it is displayed when you run the command lspci

    Based upon the output of lspci I cannot find the identifier for the webcam.

    Can someone who has experience setting up webcams pop in and give a hand? I don't know were else the device information can be located.

    I think lsusb would give the information. Give us the output of lsusb. Here's mine:

    Microdia is the webcam

    Do it means that my system knows hardware?and what can i do ?
  • mfillpotmfillpot Posts: 2,180
    Yes the one that is listed as the PC Camera is your webcam. Also after a little bit of google searching I found that someone does have drivers that work http://www.linux-projects.org/modules/mydownloads/singlefile.php?cid=7&lid=48, but it is for 32-bit, fi you are running 64-bit ubuntu then it might not work.

    Your webcam is a Microdia SN9C201.

    While I couldn't find the Microdia part number for my webcam, I did read that most (if not all) of the recent Microdia products use the uvc driver. I don't know if that's the case with the webcam in the asus, but, to check you could try:

    "lsmod | grep video" in a terminal (without quotation marks) to see if the uvcvideo driver is present.
    If not, try "modprobe uvcvideo" (without quotes) then try lsmod | grep video again and see if it's there.
    Maybe it's just not being loaded up at startup time.

    Another way to check is to install "cheese". Cheese is the one app that seems to be working (upstream took the drivers entering the kernel into account early). If Cheese works, then the problems with the webcam might be based on the apps being used to access it (folks are still having problems with kopete, skype and pidgin). You can check the Ubuntu repos for it. Or in a terminal do "sudo apt-get install cheese" (no quotes).

    Hope you figured it out already, but if not, try the above.

    It is good to see that it works, thanks to google it is far easier to find this information now.

    Also, I changed the title to reflect the device type and to state the issue is resolved to it can help guide people in the future.
