Hello, I have 2 identical Logitech C310 webcams and 2 different Linux boxes (Ubuntu Karmic 64bit, 2.6.31 AND Ubuntu Lucid 32bit, 2.6.32). None of the combinations can save jpegs directly from the camera. I always get the same error which I am starting to believe comes straight from the kernel (many different programs I've tried give the same error message). For instance:
fswebcam -v --- Opening /dev/video0...

The line with error is: Corrupt JPEG data: 1 extraneous bytes before marker 0xd1 Any hope to make it work? Please let me know if you need more data. I've used Linux for years but I am no driver/module/kernel expert. Thanks, Luke
