please add to your question the output of lsusb - need to identify how ubuntu sees your USB device. Also it would be useful to see the output of sudo lshw –  fossfreedom Jun 29 '11 at 17:21
    
@fossfreedom I added the information that you suggested. –  sawa Jun 29 '11 at 18:28

1 Answer 1

If you are lucky, your capture device will be recognized as soon as you plug it in and be ready to use. If you do ls /dev/video* you should see the device. Assuming it is the only one plugged in, it will either be /dev/video or /dev/video0.

If you don't see the device, you may have to look for the appropriate driver. This post suggest that it is really a Geniaech EZ Grabber that has been rebranded, and it uses the uvcvideo driver.

To test the device, you can use mplayer: mplayer /dev/video should do it.

I like VLC for most things, and it can do video streaming from a capture device. You can install VLC from Synaptic. VLC is pretty pretty straight forward to use, but this entry from the VLC Documentation Wiki should get you started.

Thanks for the answer. /dev/video or /dev/video1 do not seem to exist. I am trying to make the uvcvideo driver work. Search on the website suggest that ubuntu 11.04, which I am using, should have it already, but I cannot make it work. I am not sure if it helps, but I added information from dmesg to my question. –  sawa Jun 30 '11 at 15:06
    
@sawa I'm not sure what else to suggest. You might try doing an ls -lt /dev | head and see what the latest devices added were and see if they might be the correct one. Other then that, I would search the device ID (0572:262a) and see what it says. –  jwernerny Jun 30 '11 at 19:24
