Bus 001 Device 002: ID 04f2:b027 Chicony Electronics Co., Ltd Gateway USB 2.0 Webcam
This device is not working properly. I am unable to identify what driver it is or should be using. When I open Cheese all I get is a black screen.
This webcam ist supported by the uvc-driver.
Please install (as root):
zypper in lib4vl luvcview
Then start from terminal:
luvcview
‘lib4vl’ not found in package names. Trying capabilities.
No provider of ‘lib4vl’ found.
Resolving package dependencies…
The following NEW package is going to be installed:
luvcview
1 new package to install.
I could have sworn I installed it from webcam repo already.
roger@SUSE-AMD:~> luvcview
luvcview version 0.2.1

My fault, try as root:
zypper in libv4l
Then schow if it works with
luvcview
as user.
If after installing ‘libv4l’ and rebooting, and webcam still does not work, please advise:
- application you are using to test webcam ?
- whether your openSUSE is 32-bit or 64-bit ?
- output of sending in a terminal as a regular user:
rpm -qa '*v4l*' '*uvc*'
dmesg | grep uvc -iA1
lsmod | grep uvc
I found several packages of lib4vl and installed them all.

The light for the camera had turned on once… but now does not again.

32 bit Gnome
I would like to focus on the output of the dmesg and lsmod commands. Those outputs suggest to me that the uvc driver is not loading.
Here is what I get for a different UVC webcam (from those two commands):
oldcpu@corei7:~> dmesg | grep uvc -iA1
7.276397] uvcvideo: Found UVC 1.00 device <unnamed> (046d:0821)

and

You see none of that on your Gateway.
If one looks here: Linux UVC driver & tools one can see that the 04f2:b027 is purported to be a uvc webcam.
So the question is, why is the uvc driver not loading ? Is another driver loading instead ?
Now the uvc driver should come with the 2.6.37.6-0.11-desktop kernel on your PC as a ‘kernel module’. My system is a 64-bit system, and I have the kernel-default. So to locate my kernel module I would type:
oldcpu@corei7:~> rpm -qil kernel-default | grep uvc
/lib/modules/2.6.37.6-0.11-default/kernel/drivers/media/video/uvc
/lib/modules/2.6.37.6-0.11-default/kernel/drivers/media/video/uvc/uvcvideo.ko
So if you type (for your kernel-desktop kernel) :
rpm -qil kernel-desktop | grep uvc
it should show you that the uvcvideo.ko module is on your PC. Assuming that is the case, then we need to figure out :
(1) why that module is not loading, and
(2) is another webcam module loading and
(3) what happens if you manually load the module
Lets check the dmesg file to see if we can see an error message as to why the webcam module is not loading, and if another module is loading instead. Try these two commands:
dmesg | grep video -iA1
dmesg | grep cam -iA1
Lets also check to see if another webcam driver such as gspca is loading instead:
dmesg | grep gspca
that should give nothing. If it gives something, the wrong driver may be loading.
Let us know if the wrong driver is being loaded, … for if it is being incorrectly loaded, then we may need to blacklist its loading.
I also read an old Ubuntu bug report and an article (with a solution at the end) that complained on a T-1616 Gateway, that the UVC driver would not load when the wireless was active. Lets hope that is not the case for openSUSE.
To load and unload drivers, there is lots of articles on the web, such as Linux Kernel Modules - Load, Unload, Configure - Edoceo, Inc. (but I am not saying that the best article, its simple the top of the list when I surfed with google). Hence to load the uvc driver, with root permissions, something like:
modprobe uvc
or
insmod uvc
one can learn more about each by typing:
man modprobe
man insmod
…
hopefully that will get you on track a bit. Let us know if the wrong driver is being loaded.
I have upgraded to 12.1 64 bit.
Launching Cheese gives this output.

Strangely it also totally kills my wifi and I have to reboot to get it back.
CLI stuff shows thus.
linux-dbnp:/home/roger # modprobe uvc
FATAL: Module uvc not found.
linux-dbnp:/home/roger # insmod uvc
insmod: can't read 'uvc': No such file or directory
linux-dbnp:/home/roger #
I don’t use Cheese. None of that means anything to me. Can you help me understand here what it is there you think will help here and why you posted that (I’m keen to learn) ?
Not found ?? That is strange.
How can that be ? Do you have a custom kernel installed ?
Lets follow up on that. Did you read all of my post ? Did you read the bit where I explained HOW to find out if the UVC kernel module is installed on your PC ? ie on my PC’s openSUSE-11.4 partition:
oldcpu@corei7:~> rpm -qil kernel-default | grep uvc
/lib/modules/2.6.37.6-0.11-default/kernel/drivers/media/video/uvc
/lib/modules/2.6.37.6-0.11-default/kernel/drivers/media/video/uvc/uvcvideo.ko
so … try that on your PC ! Do you know what kernel you have ? To find out type:
uname -a
on my openSUSE-12.1 partition I get:
oldcpu@corei7:~> uname -a
Linux corei7 3.1.9-1.4-**desktop** #1 SMP PREEMPT Fri Jan 27 08:55:10 UTC 2012 (efb5ff4) x86_64 x86_64 x86_64 GNU/Linux
where in this case its clear I have kernel-desktop. I can also confirm that by typing:
rpm -qa '*kernel*'
which gives:
oldcpu@corei7:~> rpm -qa '*kernel*'
kernel-devel-3.1.9-1.4.1.noarch
**kernel-desktop-3.1.9-1.4.1.x86_64**
kernel-source-3.1.9-1.4.1.noarch
kernel-desktop-devel-3.1.9-1.4.1.x86_64
kernel-xen-devel-3.1.9-1.4.1.x86_64
kernel-syms-3.1.9-1.4.1.x86_64
kernel-default-devel-3.1.9-1.4.1.x86_64
again, it shows ‘kernel-desktop’ on my openSUSE-12.1 system.
So to find out where UVC video driver should be located I type:
rpm -qil kernel-desktop | grep uvc
which gives:
/lib/modules/3.1.9-1.4-desktop/kernel/drivers/media/video/uvc
/lib/modules/3.1.9-1.4-desktop/kernel/drivers/media/video/uvc/uvcvideo.ko
and its clear where the uvc video driver is located.
Please do something similar on your PC to check your pc and confirm the location of the uvc video driver. And post here the result.
Not finding the uvc driver makes no sense, unless you do not have a standard openSUSE kernel.
Thinking about this some more, I am thinking now the driver is not called ‘uvc’ but maybe called ‘uvcvideo’. So instead try:
modprobe uvcvideo
or if that fails try
insmod uvcvideo
and report here the errors you get.
I just switched to 12.1 64bit.
/lib/modules/3.1.9-1.4-desktop/kernel/drivers/media/video/uvc
/lib/modules/3.1.9-1.4-desktop/kernel/drivers/media/video/uvc/uvcvideo.ko
linux-dbnp:/home/roger # modprobe uvc
FATAL: Module uvc not found.
linux-dbnp:/home/roger # insmod uvc
insmod: can’t read ‘uvc’: No such file or directory
linux-dbnp:/home/roger # modprobe uvcvideo
linux-dbnp:/home/roger # insmod uvcvideo
insmod: can’t read ‘uvcvideo’: No such file or directory
Odd behavior. This cam worked when I tried an install of Ubuntu… unfortunately the rest of Ubuntu was horrid and broken.
Does that mean you re-installed ?
If so, the errors could be different. Please,can you then as a regular user, run in an terminal and provide the output of:
dmesg | grep uvc -iA1
and also
lsmod | grep uvc -iA1
and also
su -c 'cat /var/log/messages | grep uvc -iA1'
and enter root password in that last case. Post the output here please.
ok , so now we know the UVC drivers are present
that makes sense, as the driver syntax not called ‘uvc’ but rather it is ‘uvcvideo’
That looks promising
Now that “modprobe uvcvideo” appears to have worked (since there are no errors with ‘modprobe uvcvideo’ ) then you should not need to try ‘insmod’. Its also possible ‘insmod’ needs a path specified ? < don’t know > Lets stick with ‘modprobe’ for the time being and not use ‘insmod’ .
So after ‘modprobe uvcvideo’ what did you do wrt checking if the module/driver was loaded ? Did you try the webcam ? If so, in what apps ? And after trying the webcam, did you then look in /var/log/messages or in dmesg to see if there were any log messages giving hints as to what was working ? Also did you look for loaded modules (after ‘modprobe uvcvideo’ with the command ‘lsmod | grep uvc’ ) ?
Yes, I reinstalled the system with 12.1 64.

I’ll open Cheese, which lags a bit shows a black screen and kills my Wifi forcing me to reboot.
when you reinstalled did you also reinstall v4l ?
I don’t recommend cheese if using kde. Try packman packaged guvcview and/or wxcam.
Using Gnome now. Yes I reinstalled v4l. I assume i did it right.
Do you have a tv-card or something else installed?
Please post the comlplete output of:
