Hi all! I'm an interested person in emdbedded systems. Nowadays, I'm trying to learn Android. However I've stucked in my first try. I was working on a test project about processing video to detect motion (I'm also interested in image processing projects). In the middle of searching types of platforms, I've discovered very-mini and powerful android PC's. I've bought an OEM Android tablet pc without integrated camera. And my problem started. I'm trying to connect a USB web cam to my Android PC. It has ICS on it and supports USB Host mode. When I conenct my pendrives it automatically recognizes and I can surf in my folders using my tablet. However it did not recognize my webcam. I've made a kind of search in google and I found something called "V4L" or "V4L2". I think this is the driver that I need. However I have no idea about integrating drivers to kernel or compiling a new kernel or how to flash my tablets nand memory. I've found this link but I couldn't install the driver. Because I do not know how to integrate it. USB devices with android : Kanamaru Lab. in Kogakuin Univ. Waiting for your replies. Where should I start, what should I search and where should I start to search? Thank you very much.
