Hi everyone,
I'm using DM3730 with Android in a DevKit from LogicPD. I want to use an USB webcam but I can't. I have a Logitech c910 and it is an UVC camera:
I have followed many links and I can't find someone with same error. I just prove cam with froyo and gingerbread and I receive different errors. Obviously, I have built the kernel in both OS.
* (1) FROYO
It detects UVC cam and it creates /dev/video0: (shell)

Could you explain me why I have this error? I was seen in other post (http://e2e.ti.com/support/dsp/sitara_arm174_microprocessors/f/416/t/157015.aspx) that I should see v4l in /dev but I haven't seen it yet.

I am seeing that many people use Logitech Webcam Pro 9000 and it runs well with froyo and gingerbread. But, I think that c910 don't have many differences with Pro 9000 and it could be used with Android...
Any suggestion are appreciate.
