fswebcam not outputting a file

I'm trying to get a Logitech C510 working with my Arduino YUN.

The webcam is being recognized in dmesg and via lsusb.

However, no output is produced when I use fswebcam:

root@Arduino:/mnt/sda1# fswebcam -r 1280x720 --save /mnt/sda1/test.png
--- Opening /dev/video0...
Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
--- Capturing frame...

I've combed through here and several other sites, but can't find a solution.

Any help would be appreciated.

Thanks,

Output with -v option. It does appear to be talking to the camera without issue.

Problem is fixed.

Looks to be a power issue. I put the webcam on a USB hub and it is now working.
