Re: new sensor for a t613 camera

Hello, people.

I did it! I looked at the log and modified the driver to support my
webcam. It's working!! I'm sending an image attached. :]

I'll clean up my code now, and submit a patch later. Help is
appreciated, because I don't have much experience contributing to
large projects...

This webcam is a very cheap one, quite easy to find these days. I
hope the support will be appreciated by many users.


See you,
   ++nicolau
