Hi Daniele, Your dmesg output shows that your webcam should work:
>uvideo0 at uhub3 port 4 configuration 1 interface 0 >"CN07RGXF724879BP08ER Laptop_Integrated_Webcam_2M" rev 2.00/95.12 addr > 3 >video0 at uvideo0 If it wasn't, it would say "not configured", come up as ugen0 or not come up at all. As for the others, I couldn't say.
