Well, as told you I tried on a winXP machine. And it worked without any trouble. Excellent image.... So, it's not a hardware problem on camera... maybe something on my linux machine is not running properly. Or the driver is just not doing the proper job. I'm gonna make a few more attempts on the linux machine and post the results here.
