Perhaps the wrong driver? What made you do select uvcvideo as the driver for your webcam?

Plugged into usb:
lsusb
Post output.
Then we look up usb-ids of webcam at the Linux Kernel Driver Database: http://cateee.net/lkddb/

I would first do a lsusb command to find out the model of the webcam and also do lsmod to see what drivers have been loaded by the system. It is most likely that the system may have already loaded the appropriate driver for your webcam.

Also worth doing a Google search for linux driver for your webcam and most likely others may have already had issues with your type of webcam and may have worked out a solution to those problems.

If no luck, it may be best to post the output of lsusb and lsmod to start with.

Hmmmm ... it's a pity ... but i think there is anything wrong with the webcam driver. I verfied skype on my Netbook. Works with videosupport ....

"videodev 31754 2 uvcvideo"

Do you have 2 Webcams connected? Internal external?

no, only one O.o
does "2 uvcvideo" mean that uvcvideo 2-times(instances)-running? how to stop one instance of uvcvideo?

or, maybe, I need to do something else?

Always remove the old module before you install the new module.
Either by removing the tazpkg that owns the module or manually removing it if the tazpkg provides other modules and/or files you have to keep.
Then run this command to update the modules.dep
# depmod -a

If you installed gibors tazpkg without removing v4l-dvb-development you could have 2 uvcvideo modules on your system.If Gibor didn't compress the uvcvideo module it would have a different filename and not overwrite the existing uvcvideo.
Remove both tazpkgs that provide uvcvideo,reboot,install gibors tazpkg.
