gspca_zc3xx module

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.
