KDE 4's Kopete uses Solid to get info about present devices (it's needed by
Plug N'Play), and Solid, in Linux, uses hal, that in its turn uses some
specific properties announced by the kernel module.
Some kernel modules don't annouce themselves properly, so hal is unable to
identify them as video4linux devices, Solid doesn't see them and Kopete stays
unaware.
The problem is, in fact, in the kernel module (ov511). It's not the only module
who doesn't announce itself right, sn9c1xx and zr36060 suffer from similar
problems. I sent a patch to the sn9c1xx driver's maintainer that reportedly
fixed this problem with his drivers, but other drivers still lack an equivalent
patch.
As the problem is in the kernel module and the PnP functionality depends on
Solid, it's not viable to fix it in Kopete's code, so I'm closing this bug as
INVALID, but I ask the bug issuer to make contact with Mr. Mark McClelland
(ov511's maintainer, info at http://alpha.dyndns.org/ov511/contact.html) to ask
him to address this issue. I'm contacting him to make him aware of the problem,
but more people should contact him too imo, so he can see I'm not the only one.
;)
The following diff is the sn9cxx one I mentioned before. Someone with a
hardware sample could develop a similar patch to another module and send it to
the maintainer.
