I have two USB webcams and running 4.1.0 Linux BSP with Ubuntu Oneiric on i.MX6Q Sabre-SD They didn't work until I followed this guide to config Linux kernel. After the configuration, I can use them to take shots by the following command but not to record by application like Cheese. There's only black screen inside Cheese. Could you please help me?
