Webcam driver compilation and insertion into NanosG20

apt-get update
apt-get install make gcc dov4l libpt-1.11.2-plugins-v4l2
apt-get install subversion build-essential libjpeg62-dev libjpeg62

Need to install linux headers
Linux Kernel Quellcode Paket [85,90 MB]

wget https://www.ledato.de/download/linux-source-2.6.35.7-nanosg20.deb
dpkg -i linux-source-2.6.35.7-nanosg20.deb

cd /usr/src/linux-2.6.35.7-nanosg20
make menuconfig 

video drivers were not selected in the distro. Selected them and exit.

make modules_prepare

Started to build kernel using make, but it would take a day to compile.

Searched for ways how to compile just video modules.

Video drivers are here

cd /usr/src/linux-2.6.35.7-nanosg20/drivers/media/video

Running "make" in /video directory did not work.

Need to be here:

cd /usr/src/linux-2.6.35.7-nanosg20
make M=drivers/media/video/

Works!!! This creates .ko files. The order of insertion seems to be important.
Insertion of some modules produced error, so I ommited them.
To have the modules automatically loaded on next boot, place the code in

nano /etc/rc.local

Installing mjpg-streamer in /root folder

cd ~
wget http://sourceforge.net/projects/mjpg-streamer/files/mjpg-streamer/Source...

tar xzvf mjpg-streamer-r63.tar.gz

cd mjpg-streamer-r63
make clean all

runs 10 min, produces warnings, but exits without errors.

Example: produces information about stream and runs in foreground:

Might want to put it in background using -b.
Tried larger resolution -r 960x720 but that did not work.

Background process can be stopped by kill -9 processnr.

Is there any other way to get webcams to run with NanosG20 ?
E.g. a new kernel version or a demo image with prebuild drivers ?

I will need to get it to run for the following configuration:
lsusb: Bus 001 Device 003: ID 041e:406c Creative Technology, Ltd Live! Cam Sync [VF0520]
dmesg: usb 1-2: new full speed USB device using at91_ohci and address 3

Many thanks in advance...:-D
