I have the MSI StarCam 370i Webcam and I have trying to use it with
Kubuntu Linux 9.04 Jaunty. According to this page, "The StarCam 370i
is compliant with UVC, USB video class":

According to the Linux UVC driver and tools download page, "Linux
2.6.26 and newer includes the Linux UVC driver natively" which is nice
as I am on a higher version:
$ uname -r
2.6.28-15-generic
However, plugging in the webcam and testing with camorama, cheese, and
luvcview led me to no results:

Anything missing? What should I do? Thanks in advance!
Hello Dotan, me again ;-)
Looks like your cam is detected, but does not provide a good frame
format. You my have to use libv4l to convert to a know format.

Description: Collection of video4linux support libraries
libv4l is a collection of libraries which adds a thin abstraction layer on
top of video4linux2 devices. The purpose of this (thin) layer is to
make it
easy for application writers to support a wide variety of devices without
having to write separate code for different devices in the same class.
libv4l
consists of 3 different libraries: libv4lconvert, libv4l1 and libv4l2.
.
libv4lconvert offers functions to convert from any (known) pixelformat
to BGR24, RGB24, YUV420 and YVU420.
.
libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices,
independent
of the drivers for those devices supporting v4l1 compatibility (which many
v4l2 drivers do not).
.
libv4l2 offers the v4l2 API on top of v4l2 devices, while adding for the
application transparent libv4lconvert conversion where necessary.
.
This package contains the shared libraries.
