Microdia webcam in 12.2
I had a microdia webcam working in 12.1 with the driver compiled from the source available at that time from

However after a fresh install of 12.2 and a download of the current source from the microdia site I have had little success in getting any worthwhile video output in either xcam or mplayer. It seems there is something changed probably as the driver code is in a constant state of develoipment. I note that libv4l is required now with this driver and it is installed.

Has anyone else had any success with the sn9c20x driver. In my case, the webcam details are idVendor=0c45, idProduct=6242.

wow this has been gone over many times ok. the new kernel has limited drivers un like the old ones from the 2.6.24 kernel ok so what we been doing is go to /lib/modules/ and there you will see gspca_main cut and paste it some where for safe keep. now go here and download. alien Bob is a wonderful guy if you see his post thank him. reboot and all should be well that is exactly what I did. or you can use his build

Yes I know that this has been gone over many times ok and I know about the gspca driver and Alien Bob's gspca package provides a driver that works just fine with our Logitech Quickcam

However gspca does not provide any functionality with this here microdia webcam and the microdia driver source I was referring to comes a group of folks trying to hack out a fully functional driver.

I had success with their very beta driver downloaded last year and installed on 12.1 however their current source did not work for me with 12.2 and I was asking if anyone else might have had some success with it.

I'm not quite sure if that has been gone over before on this list but I've been wrong before.

Yeah .... Alien Bob's allright too.

hey did you check out this thread they are using intrepid kernel I will keep reading on this also hardware is my thing and the kernel changes that have happened in the last year has really kept me on a learning curve. hang in there.Here is the driver I just built it. but I do not have the cam to test it on.

cd ~/Documents
mkdir webcam
cd webcam
git clone

Note: If you have any of the following Microdia cameras, you’ll need to switch to the Experimental branch:

6242, 624e, 624f, 6270, 627b, 62bb, 145f:013d, 045e:00f4

Switch to the Experimental branch by running:

git checkout --track -b v4l2-experimental origin/v4l2-experimental
last but not least go here and read some more.

Thanks for your interest. That link to 64bitjungle debian howto is from August last year which was around the time when I successfully built modules that worked with my 6242. The guys working on the microdia ocde have moved on since then and now there is a dependency for v4l2 libs. I had errors pointing to v4l2 the last time I had a go at this using mplayer. I had used a pkg from I later picked up the source and compiled my own but have not gotten around to doing anything more about it since the webcam is for my daughter to use and it is not a big priority for he right now.

I'll let you know if I make any progress.

I did some big reading on this and got some stuff working on the kernel went and got the newest xawtv and it is built to work with v4l2 I also built camorama but i had to do this to get it to work

LD_PRELOAD=/usr/lib/libv4l/ camorama
I know I only have a pixart cam and I already have it working in slackware sorry I have been trouble shooting hardware on linux mint6 and not to happy with it . but what it does have in common is instead of using the old pac207 when I did alien bobs gspca build. I did this from source and wanted to use the new pac207 and the new gspca_main and make it work got everything to work with the cam except gyachi.
Again I know they are different cams but really we are both trying to get the new kernel v4l2 to run on the new kernel modules. and this has to do with the gpl licence and going to v4l2 and running it in users space to keep things running through libraries instead of getting a license for every device or programs. hang in there
