fswebcam returns VIDIOC_DQBUF: No such device error

I have a logitech c270 connected to my arduino and I'm using fswebcam but it doesn't work.

root@Arduino:~# fswebcam

Power issue?
Thanks

That would be my guess. The Yun is a power hungry little board, and webcams add to it. How are you powering the Yun? I have run the yun and a WC off a 1600mah 7.4v lipo. I have also used a good USB power bank (2600mah). Both seemed to run the cam and Yun fine. I will say that the Yun shields seem to be more power intolerant then the real Yuns are.

@jscottb,
the Yun is not power hungry - in comparison to other boards. But, yes, add the camera and it is possible that there is not enough power.

I like the power banks, but other people would recommend a power wort.
