Hello, I already tried compilling all the branches from SVN, I always get
something similar to this:

make -C /lib/modules/2.6.28-gentoo-r5/build

I removed references to owner and type usb_m5603c_probe instance members in
m5603c.c and it compiled now.

Now with  I get this at connect:

Also, red LED on the device turns on for the first time and I get
/dev/video0  :) This is however where functionality ends, cheese doesn't
find it using HAL and mplayer sez:

Thanks for such prompt answer :) I'll go poking with the struct, I presume
the code is obsolete with some v4l change now ?

[M560x-driver-devel] Genius slim321c webcam

[Jakub N. <jc....@gm...>]

Hello,
first of all, thanks a lot for all effort you do to help v4l work :)

I have a Genius slim 321C webcam with lsusb (full output below): VID:PID
0402:5603 ALi Corp. USB 2.0 Q-tec Webcam 300
the exact VID:PID I found in m560x-driver documentation.
Please note: contrary to documentation, 0402:5603 isn't bound in the driver,
only 0402:5602 is. I had to change it in m5602_core.c to make it work.

dmesg/syslog:

I tried forcing individual sensors each time replugging the cam, still
mplayer green screen/cheese hangs.

Any answer much appreciated. I'm willing to help, I can apply
patches/recompile without problems.

I've been thinking this over and decided that I don't want/need any
bounty. I did my part of the development because I found the problem
interesting.
If you really want to depart with your hard earned money I'd suggest
you donate it to an organization fighting for electronic freedom
(EFF, etc.)

Thanks for your initiative though!

Best regards,
Erik

Linus ? no needs for him I think.
Better to organization like 'april.org', a french one.
If Sam determines a quota for me, I give it to 'april.org'. Good idea.

I think the spirit of open source is to build/extend on what everybody 
contributes.
Either give the bounty to Linus or some other noble goal.

Personally I think bounties are not the driving force and are useless, 
but if people want to claim: let the bounty hunters be happy.

Erik yes, 

Alone, no ;-)

The actual working driver m5602 is integrated into the GSPCAv2 architecture
mainly launched by Jf-Lemoine (video for linux v4l-dvb).

I have suggested to use the gspcav2 model for Erik's driver (m5602)
I made a first shot of a working driver for the m5603c standalone and gspcav1
I also moved to gspcv2 this driver (m5603c)
The very first m5603c had never really worked.

Unfortunatly, the m5603c seem to be less common then the 5602 so I don't
have a lot of returns.

  Today I booted an ubuntu jaunty kernel on my Acer laptop and the webcam

Would those who have contributed largely to this success and who thus

I'll give it a couple of weeks and then I expect to declare the bounty

Hi all,

I've added image flipping support for the Asus A6VA in m5602_ov9650.c.
It appears to be one of the models that have the camera mounted upside-down.

Attached is my patch against the mercurial repository's tip.

Hi,
The driver is already upstream in the linux kernel since 2.6.28.
I have a repository hosted at www.linuxtv.org where I put in my
changes which then are sourced into linux-dvb when I request it.
This tree is in turn pulled by linus.

Dear all , 
   I just wonder that this driver work on almost right now , Is it
possible to embed in Linux core, thus everyone can use and no need to
install driver.

hi,
thanks for reminding me on this issue.
Just to get a stable point of reference.
Is the issue still present on the upstream version available at
http://linuxtv.org/hg/~eandren/gspca-m5602/
Please see http://m560x-driver.wiki.sourceforge.net/testing_m5602
for more information.

Regards,
Erik

Dear devs,

my camera is still showing me vertically rotated pictures as you can see here:

In s5k83a world is "sd->sensor_priv" pointer to "s5k83a_priv" struct, instead 
s32 array as in other sensors. 

So, we need 

((struct s5k83a_priv*)sd->sensor_priv)->settings;

instead

sd->sensor_priv;

for get pointer to ctl cache (s32 array).

[Lukáš K. <luk...@ce...>]

Hi Erik.

I tested your cleanup in s5k83a init sequence today. It work fine in all my 
test (after clean boot, reboot, resume from suspend (s2ram) and resume from 
hibernate (s2disk)).

I found small, but dangerous error in s5k83a init function during tests. This 
error set incorrect default ctl values after init. In attachment is patch for 
fix this.

By the way, I look up to your pertinacity. All respect!

Hi,
I'm aware that reading the po1030 sensor is broken.
As the usb snoops never reads the sensor it's hard to determine the
proper procedure.
I've tried to locate such a function in the windows driver but have so
far been unsuccessful.

Erik

[Laurent B. <du...@gm...>]

Hi,

My hardware reconnect problem is resolved since 367955b3f421 revision
but i think there is something wrong, some dump sensor values change
when i reload the module :

it seems some values moved on the top each time i reload the module
(with dump_sensor option).

See my sensor dumps made after 3 module reloading.

Hi,

Now, i can switch in 640 to 320 and come back in 640 without problems.
But in qvga mode i don't get a good image, see my records made with cheese :

No, not really as I've still not understood the core cause of it.
So it's working now?

Hi,

Yes, i'm willing to work with you.
I may not have much time then it will take certainly more time.

My competences are limited, i don't understand all you made in driver
source but i can try, test and report.

It seems i have no more the hardware reconnect problem (disconnect
sequence) but i don't see nothing about this on changelog.
Have you made something to resolve it ?

Regards,
Laurent

I realise that getting QVGA to work properly is going to be a bit of
trial and error. Are you willing to put some time into getting to

Otherwise I'll just disable that resolution and be fine with it.
