v4l2 and /dev/video0

Hey, I got a usb video capture dongle. It uses stk1160 driver. I heard the stk11xx driver in AUR works.
my problem is I don't understand video and linux. Where or how do I get the v4l2 and this /dev/video0 shows up no where.

dmesg|tail
agpgart-via 0000:00:00.0: putting AGP V3 device into 8x mode
nvidia 0000:01:00.0: putting AGP V3 device into 8x mode

What's the exact problem?

Your system can detect it, as you see:

thanx djszapi.
yes my system can dectect it but I see no /dev/video0 or anything like that. I read that I was suppose to see that under /dev.
The apps I use look for the device there too.
I'm trying to use the video capture usb dongle.

Re: v4l2 and /dev/video0

Do you have the desired udev rules for it?

/etc/udev...

Please check it, if you haven't got the desired rule for it, you must write it manually, but not so hard.

Re: v4l2 and /dev/video0

time to slap me... how do I do that?
/etc/udev
I have these: rules.d  udev.conf
under rules.d:
54-gphoto.rules                             97-bluetooth-serial.rules
60-pcmcia.rules                             99-fuse.rules
75-cd-aliases-generator.rules.optional      device-mapper.rules
75-persistent-net-generator.rules.optional  kino.rules
90-hal.rules

yeah, from the wiki, it says ls /dev/v4l
or ls /dev/dvb

ls /dev/v4l
ls: cannot access /dev/v4l: No such file or directory

ls /dev/dvb
ls: cannot access /dev/dvb: No such file or directory
