This looks alright. Just to be sure, try to raise the brightness level in luvcview. > Another question, when I do a lsmod | grep uvcvideo I have : > > uvcvideo 53508 1 > compat_ioctl32 17217 1 uvcvideo > videodev 36673 2 uvcvideo > v4l1_compat 20549 2 uvcvideo,videodev > v4l2_common 28353 3 uvcvideo,compat_ioctl32,videodev > > Reading some web stuff, I showed that there was an 'usbcore' module but if > I try to load it it send an error because it is not found.. > > Does uvcvideo needs the usbcore module? The usbcore module is probably included in your kernel. Loading uvcvideo would fail if usbcore wasn't loaded and couldn't be loaded. There's nothing to worry about there.
