Kernel is Debian 2.6.32-41, which is closely based on stable
2.6.32.54.  I don't see any obvious potential fixes in the diff
relative to linux-next.

Known problem?  Any hints for tracking this down?

Thanks,
Jonathan

Hi Skippy and Jonathan,

The git commit b877a9a7fb0 (gspca - ov519: Fix sensor detection
problems) may have fix this problem.

To be sure, try the gspca test version from my web site.

Oh!  Yep, the symptoms match well --- sorry I missed it.

Skippy, assuming that works (and I expect it would), could you try the
attached patch against 2.6.32.y?  It works like this:

 0. Prerequisites:
	apt-get install git build-essential

 1. Get the kernel, if you don't already have it:
	git clone \
	 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

 2. Fetch point releases:
	cd linux
	git remote add -f stable \
	 git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git

 3. Try the 2.6.32.y branch:

	git checkout stable/linux-2.6.32.y
	cp /boot/config-$(uname -r) .config; # current configuration
	make localmodconfig; # optional: minimize configuration
	make; # optionally with -j<num> for parallel build
	fakeroot -u make deb-pkg
	dpkg -i ../<name of package>
	reboot

    "make localmodconfig" works by leaving out drivers whose modules are
    not currently loaded, so take care to make sure the gspca and ov519
    modules are built.  ("make nconfig" customizes the configuration.)

    Hopefully this kernel reproduces the bug.

 4. See if the patch helps:

	git am -3sc <path to patch>
	make; # maybe with -j4
	fakeroot -u make deb-pkg
	dpkg -i ../<name of package>
	reboot

Hopeful,
Jonathan

Subject: [media] gspca - ov519: Fix sensor detection problems

commit b877a9a7fb00d96bae4ab49c69f1be65b3e87e61 upstream.

The sensor of some webcams could not be detected due to timing problems
in sensor register reading. This patch adds bridge register readings
before sensor register reading.

This asks for a lot of job. With the gspca tarball (423Kb), you just
need the linux-headers. And it permits further debugging...

Do you mean bandwidth?

I expect that this is fixed in 3.x.y already, so I wanted to confirm
that that is the only fix needed to get it fixed in 2.6.32.y-longterm
as well.

Kind regards,
Jonathan

The compilation failed (see at the end of this email) and I didn't feel 
like trying to debug it so I went for Jean-François' build, and it seems 
to work fine (thanks !).

<HS>Jean-François, please have a look at
