[linux-uvc-devel] Problem with webcam ID 1bcf:2082 Sunplus Innovation Technology Inc.

[Ivan Paes José]

Hello,

I am contacting you to expose the problem I'm having with my webcam.
Before continuing it is necessary to explain that I am not developer'm just
a Linux enthusiast and would like my Webcam to work on linux.
I made several google search to see if someone is in the same situation as
me the answer is yes. But there is no solution.
So I made a more detailed search and came to the linux-uvc project. I did
the search on compatible devices page and mine is not.

problem:

In dmesg my webcam is: HD WebCam

When opening the cheese the error occurs: "An error occurred while playing
the video from the webcam"

After that the other located uvc webcam: SPCA2082 PC Camera

However, if you use VLC: VLC v4l2:///dev/video0 can have image smoothly.
note: vlc only works when you are with HD WebCam. After opening the cheese
that changes to SPCA2082 PC Camera does not work anymore.


I could not enable trace the uvcvideo

~$ sudo echo 0xffff > /sys/module/uvcvideo/parameters/trace
bash: /sys/module/uvcvideo/parameters/trace: Permission denied

The lsusb -d 1bcf:2c32 -v > lsusb.log occur after the problem has no output
at all. Only after reboot and the divice is HD WebCam

If you need any more information please inform.

Regards,

Ivan Paes José

bash: /sys/module/uvcvideo/parameters/trace: Permission denied

sudo does not apply to the redirection.
You should do
$ sudo su -
# echo 0xffff > /sys/module/uvcvideo/parameters/trace
# exit
$

Or the tee hack!
echo 0xffff | sudo tee /sys/module/uvcvideo/parameters/trace
