I've used the uvc_cam package for a number of webcams, including a Logitech Quickcam and a Microsoft Lifecam.
Hi Harmish,
I have had good results using the usb_cam driver on my Logitech Quickcam Pro.
I did not have to edit the source code, but I did need to provide a new pixel format as a parameter. Try using this launch file:
<launch>
<node pkg="usb_cam" type="usb_cam_node" name="cam">
<param name="video_device" value="/dev/video0"/>
<param name="pixel_format" value="yuyv"/>
</node>
</launch>

hello,
i am trying hard to make logitech quickcam pro 4000 to work with ros. i have tried following drivers without sucess.
gencam_cu - problem to link wiht libroslib.o - recompiling does not solve the problem !!
logitech_usb_webcam - making does not give any executable
usb_cam - has problems with ioctl(fd, VIDIOC_S_FMT, &fmt) - gives error 22 - invalid parameters
uvc_cam - has problems with ioctl(fd, VIDIOC_S_FMT, &fmt) - gives error 22 - invalid parameters - i succeed in bypassing these errors by changing fmt.fmt.pix.pixelformat to V4L2_PIX_FMT_YUV420 and changing buffersize (NB_BUFFER = 2), however now i have segmentation fault
if anybody have success running a webcam with ros, i would be thankful to know the driver and camera you are using.
cheers,
harmish.
