I'm curious to see what I need to get this camera up and working. I plugged it in, nothing happened. I specified local and /dev/video0 but it just won't work. Is there a driver involved? Forgive my n00bness on this.
What's really strange is that I pretty much had the IP cameras up and running within an hour, which I thought would be harder. Seems the other way around, USB is more difficult.

--------------------
The format is the one that is stumping me. I don't know if that's what's keeping it from working. Format 49150 doesn't correspond to any in the ZM list like NTSC or PAL or etc...
I used 640x480, 320x240, changed to pal, nstc, etc. but no luck.

Solved it's a permissions issue with /dev/video0
