How to get USB camera working on Beagle Board

[sri]

Hi ,

I have connected Logitech camera to the USB hub, BB is detecting the
camera when board is booted and lsusb , dmesg | tail commands also
displaying the device.Here I am confused about camera is working or
not if works how to view the captured video on beagle board.


I have downloaded the files from the below source

http://www.angstrom-distribution.org/demo/beagleboard/ or Do I
need to build rootfs on my own.???????

1) Partitioned the hard disk (FAT 32, Ext3 formats)
2)Copied MLO,uImage.bin(2.6.29),U-boot bin into FAT 32 file system
3) Untar the Angstrom image into the ext 32 partition
4) unzip the modules file into /lib/modules in ext 32 partition
5) setting environmental variable

Angstrom is loaded,
Mouse and Keyboard are working fine.


Please suggest me if I have done any mistake in above procedure


Thank you

Do you use a self powered USB Hub to connect mouse and keyboard? Coz
on my hub it's not working ... :(

Hello, Perhaps I can give you what works for me. I use a Logitech
QuickCam Chat USB webcam (non-UVC).

here is dmesg when webcam is plugged in.

Three working commands to test:

Works on sony-desktop and Beagle sakoman build ( my current is
build date 05092009)

mplayer tv:// -tv driver=v4l2:width=320:height=240:noaudio:device=/dev/
video0 -fps 15 -vo xv


Works great on Beagle: (-fps optional)
