Bug 477111

http://moinejf.free.fr/webcam.html shows this webcam as "not tested" but having the same sensor as the Philips spc 700 nc (0471:0328) with works with sonixj under
gspca v4l2.

Hi,

Sorry it took so long for this to get assigned to me . I'm Fedora's webcam expert and one of the gspca authors. So the problem is the sn9c102 driver which has been
part of the kernel for a while now, sucks, as it claims to support devices
which it doesn't.

When we added gspca to the mainline kernel, when a USB-ID was already claimed
by the sn9c102 driver, we added it to gspca the following way:

#if !defined CONFIG_USB_SN9C102 && !defined CONFIG_USB_SN9C102_MODULE
        {USB_DEVICE(0x0471, 0x0327), BSI(SN9C105, MI0360, 0x5d)},
#endif

This means then when you build gspca from source, or as part of the kernel and
the sn9c102 module is enabled, we won't include the ID (to avoid conflicting
with sn9c102 and causing potential regressions for users of sn9c102).

Slowly as we get more reports like yours, we remove the ID's from the sn9c102 driver and add them unconditionally to the gspca driver. Sorry about all the pain
this causes.

So what I would like you to do, is get the latest gspca tree from:
http://linuxtv.org/hg/~jfrancois/gspca/

Like you did before and then edit linux/drivers/media/video/gspca/sonixj.c, and
remove the #if ..., #endif around the USB id for your cam. Then make sure you do
not have sn9c102 loaded, and you do have gspca_sonixj loaded, and then plug in
your cam.

Hopefully things will then just work, if that is the case I'll do a patch
removing the USB-ID for your cam form sn9c102, and removing the #if #endif from
sonixj.c

Thanks!

Thanks very much; what you said to do works perfectly!

I removed the #if ... #endif around line 2231 in linux/drivers/media/video/gspca/sonixj.c.  Then make; make install; and reboot.

The sn9c102 module still loads when I plug in the webcam, but I guess gspca takes over:

I tried using the camera with "camstream" and it works perfectly.  

-------------------

This is a different topic, but since you're the Fedora webcam expert and since it's good news rather than more problems, I might mention that I have another webcam that works out of the box and is
listed as "untested" at http://moinejf.free.fr/webcam.html.
I can report this somewhere else, if it's more useful.

This is the working camera:

ov519	041e:4061	Creative Live! VISTA VF0400	?? 	not tested

Here are the messages when it's plugged in:

This used to be supported by the ov51x_jpeg driver that I found at
http://www.rastageeks.org/downloads/ov51x-jpeg/ov51x-jpeg-1.5.8.tar.gz.
I was surprised and pleased to see it just working with the 2.6.27 kernel.

------------------------

Thanks again for your great work!

Thanks for testing!

Patch send upstream making this cam be handled by gspca instead of sn9c102 out of the box. It will end up in Fedora's kernel in due time through upstream.

p.s.

Its the best if you submit info like this directly to JF Moine:
Jean-Francois Moine <moinejf>

Thanks.
