Fedora 16(x86_64) (for reference): 160x120 176x144 320x240 352x288 640x480 It appears that the webcam drivers for ARM have some room for improvement. I'm curious how you got mjpg-streamer to compile on the Raspberry.
However, using mplayer I just get a timeout like with my other two cheaper webcams. My specific error is: v4l2: select timeout (and as with my other webcams, the C310 does work fine with mplayer on a x86 Debian system.) As I said in the first post I'm using "wheezy" images from but I made an update (apt-get).
Can you specify exactly what software and what command you use to have it working? I won't be at home for the weekend so I'll be able to send you the exact kernel version later on PM.
I believe this is a network problem and it has nothing to do with the camera. My RAM split is 128/128 right now although I also tried giving the GPU the minimum.

Selected driver: v4l2 name: Video 4 Linux 2 input author: Martin Olschewski comment: first try, more to come ;-) v4l2: your device driver does not support VIDIOC_G_STD ioctl, VIDIOC_G_PARM was used instead.
When the camera is plugged the uvcvideo driver is auto loaded and everything looks fine. 640x480, 352x288 are just showing black screen and CPU is at 0% load.
