[linux-uvc-devel] SunplusIT PC Camera ID 1bcf:0b01 , timeout trouble

[Bruno Friedmann]

Hi all,

I'm looking for a way to make my Dell Precision M4600 integrated webcam working.
I'm using a openSUSE 12.3 with a kernel 3.12.4 actually.

When I want to use it, I got timeout

for example with
guvcview
guvcview 1.7.0
file guvcview_video.mkv has extension type 1
file guvcview_image.jpg has extension type 0

Bunch of information :

ll /dev/video0
crw-rw----+ 1 root video 81, 0 Dec 13 08:43 /dev/video0
c-3po:~/bin # getfcal /dev/video0
If 'getfcal' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf getfcal
c-3po:~/bin # getfacl /dev/video0
getfacl: Removing leading '/' from absolute path names
# file: dev/video0

Look like there's no rights trouble.

removing or inserting the module works here is with trace 255
