Hi guys,

I have found a few issues:

1- Repos Access Instructions Wrong:
I can not download the repository with the commands listed in the
online instructions at (http://groups.google.com/group/microdia/web/
testing-microdia-driver-draft):

$ git clone http://repo.or.cz/r/microdia.git
error: Can't lock ref

$ git clone http://repo.or.cz/microdia.git
Cannot get remote repository information.
Perhaps git-update-server-info needs to be run there?

I have to change the http: bit to git: then it works
$ git clone git://repo.or.cz/microdia.git


2- Driver Doesn't Work Anymore:

My webcam is 0c45:6270 Microdia U-CAM PC Camera NE878, I used to be
able to use this driver on an older machine with kernel 2.6.18 but it
has since died and I moved to a machine with 2.6.24 kernel. I have
successfully compiled and load the module (using both the old source
code I used last year, and the lastest microdia source code) on this
new kernel, however nothing works.

On module loading dmesg show every OK:
--
sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:6270 plugged-in.
sn9c20x: Detected MT9V011 Sensor.
sn9c20x: Webcam device 0C45:6270 is now controlling video device /dev/

usbcore: registered new interface driver sn9c20x
sn9c20x: SN9C20x USB 2.0 Webcam Driver v2009.01 loaded

Howerver tests with mplayer (as instructed in online instruction
above) has this error:
--
$ LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so mplayer tv:// -tv

Test image capture with streamer also creates errors:
$ streamer -c /dev/video0 -o test.A.jpeg
files / video: JPEG (JFIF) / audio: none
no way to get: 320x240 JPEG (JFIF)
movie writer initialisation failed

When these errors occur, dmesg spit out these messages:
sn9c20x: Using yuv420 output format
sn9c20x: Using yuv420 output format
sn9c20x: Using yuv420 output format

Anything I can do to help with debugging the problem?

Thanks and keep up the great work guys,
Vinh
