Hans,
I'll have more later, but I can say, if LED API is what we agree to, we should
have infrastructure in v4l2 at a level higher than gspca for helping drivers
use the LED interface and triggers.
Specifically this is needed to make discovery and association of v4l2 devices,

I'm of the mind that independent boolean illuminator controls are Ok. I think
that scales better. Not that I could imagine many in use for 1 camera anyway,
but some may be colors other than white.
Illuminator0 should always correspond to the most common default application of
the device.

Hans de Goede,
The uvc API that creates v4l2 ctrls on behalf of userspace could intercept
those calls and create an LED interface instead of, or in addition to, the v4l2

Until udev, hal, pam, and polkit userspace configurations catch up, one still
