Hi, I also have a similar problem now with 0.9(3) with my raspberry camera module. It worked fine in version 0.8(x) for still pictures. But now I cannot stream video or take pictures from Astrobox (local ip) or astroprint.com.
The camera is detected and I can set format, resolution and fps. But none of the combinations work (I tested in Chrome or Safari). From astroprint.com I get the error something about changing resolution. From the local ip, it just gets stuck in e.g, "taking picture" and nothing happens. I can take pictures with raspistill and also access the camera stream with ssh in Android.
I have not tried with other camera (I have no usb cameras), but I plan to get a cheap one and try later
