Hallo,
I found in this list message Logitech QuickCam Pro for Notebooks
046d:0991 not working from Mon Jul 28 10:18:08 CEST 2008. So now i will
ask about same problem. It seems some bugs was fixed, some new probably
made.
I have some random problem with this camera. Thirst of all cheese, some
fine, others the camera just crashes and I need to
unplug it so
that it will work again.
Other apps work just fine with the camera.
Best regards,

Hi,
i helping my friend to install linux on his new laptop fujisu lifebook
a340. It is cheap one (350€) but seems to work good with linux. But web
cam has some issues, which i will discuss with you.
It is uvc webcam (0408:1fc3 Quanta Computer, Inc.). For most frame sizes
it aims to support 10,
can you please send ouput of this command uvcdynctrl -f
what do you mean with refresh rate? if frame rate, do you mean it is too
high?
Please install gstreamer0.10-plugins-bad and try this command:
gst-launch-0.10 -v v4l2src ! video/x-raw-yuv,width=640,height=480 !
ffmpegcolorspace !
Ok, i thought you get images where 3/4 will be black and 1/4 is actual
image. Now i see it looks more like zoom (like sw zoom on my logitech).
Seems like your problem is the eeprom (sort of BIOS) of your webcam. It

in this log i see only the usb-host part. Can you please reload uvcvideo
module with:

on my logitech cam you can bring it to freeze if you starts the video
and stop it before it actually starts. So may be your app send some
text on monitore
(lots of light, high fps) is about 3bpp.
So we can calculate predictable buffer size in driver, insted of
getting some random numers from the cam.
Setting bpp to 4 for mjpeg should be safe.

Hi,
you do not need to send any webcams, (but if you will, i'll accept it :D)
better attach output of lsusb -vd 177f:0060
, also enable trace for uvc module, reporoduce this error and attach the
dmesg as well:
sudo rmmod uvcvideo sudo modprobe uvcvideo trace=0xfff

Hi,
to get the idea of what is wrong here, we need at least dmesg. If you
can't provide dmesg, but you can compile kernel, do git bisect.
There is lots of howtos in internet about git bisect:

can you please apply this patch on top of current kernel git.
With this patch you can get access to some webcams infos without
