Running a 2.6.11 kernel and have encountered the following problem.

i've installed the ov51x driver for my ov530 webcam and am attempting to get a jpeg from it.

i run the command

./getjpeg -d /dev/video0 -s 640x480 -o test.jpg

and recieve the error message

Could not open device /dev/video0

the command dmesg says there is a usb device recognized
it says

usb 2-2: new full speed USB device usign uhci_hcd and address 2
usbcore: registered new driver snd-usb-audio

I have followed all the instructions outlined at http://www.ovcam.org/ov511/install.html

and that all seemed to work fine, but it can't seem to find my camera at /dev/video0 and I checked my distro, it's not one of the ones that has /dev/video as a directory.

Any body have any ideas?
