Hi, I'm a newbie here.
I have installed squeeze and kernel 2.6.32-3
Also I use the USB webcam Asus.

A week ago I installed lenny, my webcam didn't work, then I made upgrade to squeeze and my webcam worked! I don't know why
Yesterday I have installed the system again, the base system as lenny (net-install) and then squeeze. But webcam doesn't work

So, I don't know what should I do? I use cheese and It writes camera not found.
Any ideas? Thank you!

cheese failed with me before, I found it was using an invalid image size. You can force it to use a certain image size in its configuration file ~/.gconf/apps/cheese

I also like wxcam, I had no problems with that program

Excuse me, but the issue is solved. I've forgotten to install hal and gnome-device-manager, after that the camera is ok
