Webcam won't work

[Zhmak]

Got Ubuntu 10.04 beta1 on ASUS EEE PC 900

Can't take video from Chicony CNF7129

zhmak@zhmak-eee:~$ gstreamer-properties
libv4l2: error turning on stream: Input/output error
gstreamer-properties-Message: Error running pipeline 'Video for Linux 2 (v4l2)': Error starting streaming on device '/dev/video0'. [gstv4l2object.c(1952): gst_v4l2_object_start_streaming (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src1:
system error: Input/output error

Webcamera LED indicator doesn't blink while trying get video.

Part of dmesg

Webcamera worked well on Ubuntu Karmic without any manipulations.

I'm sure there is not a darken image at video stream. I know how to adjust brightness\contrast. There is no video at vlc or cheese.

I made clean install of lucid beta2. Having the same problem.

Also I'm still think, that is'nt duplicate of bug #542042. I'm have no video stream instead of darken or black blank screen.

I'm sorry.

Webcam works fine now. I needed to switch "OS Installation" to "Finished" in BIOS.
