    problem with my webcam

    hello everyone

    i am using ubuntu 10.10


    i have got my z-star microelectronics usb 1.1 webcam connected in my pc. when i use camorama or cheese booth, the green indicator of webcam appears but webcam doesnt show any image. when i put it in bright light source, it shows the bright light but it goes dark for normal objects. i am new in ubuntu. i have put the lsusb report as follows

    Bus 002 Device 003: ID 0ac8:307b Z-Star Microelectronics Corp. USB 1.1 Webcam

    i have checked the device settings using ekiga and have found that it is using v4l2 platform. what shall i do. if i plug in creative webcam, it responses properly but with z-star webcam it doesnt work. is it the compatibility issue.

    hoping for your kind reply

    Have you tried luvcview?
    It helped me get my UVC compatible webcam working. And let me know when an outdated web cam didn't.

    --del
    error! ulimit exceeded for /dev/null
