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.

Re: new sensor for a t613 camera
I wrote an e-mail to the company that seems to have designed this camera of mine, the German LogiLink, and they answered me this morning. Looks like the camera uses the CNLTF LT-168G sensor. Searching for the terms in Google shows some hits regarding the microdia driver, so it might be possible we can even take some stuff from them... Is this true? So, should I try to get the log anyway, or can we try to do something else now that we have this clue?

Re: new sensor for a t613 camera
OK, I'll try to get a windows box and log it. I believe the original designer of this camera is a German company named Logilink. I wrote an e-mail to and address in their website, let's see if there is any feedback. ++nicolau On 11/13/09, leandro Costantino wrote: > Hi Nicolau, > Are you able to give me some usb traces? > there's a little how to > > http://deaglecito.blogspot.com/2008/10/new-sensor-merge-faq-tascorp-17a10128.html > here. > > I don't have too much time now, but i can take a look and made some > changes to test and guide you. > > Best Regards > Costantino Leandro > -- Nicolau Werneck 25A1 1BCB 714C 29E7 D84C http://www.lti.pcs.usp.br/~nwerneck 8514 152D 103F B001 8740 Linux user #460716 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: new sensor for a t613 camera
Hi Nicolau, Are you able to give me some usb traces? there's a little how to http://deaglecito.blogspot.com/2008/10/new-sensor-merge-faq-tascorp-17a10128.html here. I don't have too much time now, but i can take a look and made some changes to test and guide you.
