gspca_zc3xx module

[Hasan SAHIN]

 Hello Jean-Francois,

I am using Gentoo linux stable x86 with kernel 2.6.34-r1.
before the kernel update to 2.6.34-r1, I was using 2.6.32-r7 and there 
was no problem with webcam.
The webcam was working as good with kernel 2.6.32-r7(old gentoo stable 
kernel)
but right now it does not work with the kernel 2.6.34-r1 (new gentoo 
stable kernel)


And also I have tried with ubuntu 10.04 (kernel 2.6.32-25) and working 
good. I could not understood what is the problem. (Problem is : there is 
no output, no stream)


All test has been done with wxcam,cheese and your svv.c program.

Could you please help me?

Thanks and regards,
Hasan.

Hello Hasan,

In the kernel 2.6.34, the sensor mi0360soc sequences have been changed
to make the webcams 0ac8:301b work, but these sequences are wrong for
the webcams 0ac8:303b.

An other user is testing the fix which is in my test tarball (see my
home page below - current version 2.10.4). There is just one remaining
problem: the image is mirrored, and I have not found yet how to set it
normal...

Best regards.
