2009-08-13V4L/DVB (12380): uvcvideo: Avoid flooding the kernel log with "unknown event ↵Laurent Pinchart
type" messages The iSight sends non-UVC status events through the interrupt endpoint. Those invalid events are reported to the kernel log, resulting in a log flood.

2009-06-16V4L/DVB (11837): uvcvideo: Start status polling on device openLaurent Pinchart
Most UVC camera include an interrupt endpoint to report control value changes, video streaming errors and camera button events. The USB controller continuously polls the interrupt endpoint to retrieve such events. This prevents the device from being auto-suspended, and thus consumes power. Reporting video streaming errors don't make sense when the V4L2 device is closed. Control value changes are probably useless as well if nobody listens to the events, although caching will probably have to be completely disabled then. No polling is thus be required when /dev/videoX is not opened. To enable auto-suspend and save power do not poll the interrupt endpoint until the device is open. We lose the ability to detect button events if no application is using the camera. http://bugzilla.kernel.org/show_bug.cgi?id=11948 Signed-off-by: Laurent Pinchart <laurent.pinchart@skynet.be> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-29V4L/DVB (9661): uvcvideo: Commit streaming parameters when enabling the ↵Laurent Pinchart
video stream Sonix-based cameras seem to require the host to commit video streaming parameters before selecting the alternate endpoint. While most applications issue a VIDIOC_S_FMT ioctl before starting streaming, this is not required by the V4L2 specification. The problem has been noticed on Ubuntu 8.10 with applications using libv4l. The library blocks VIDIOC_S_FMT calls when the requested format is identical to the currently selected format. As the driver commits video streaming parameters when initialising the device, only the first run of a libv4l-enabled application would succeed. For the sake of completeness, experiment showed that the camera keeps sending 12 bytes isochronous packets (header only, no data) without toggling the FID bit if video streaming parameters haven't been committed before selecting the alternate endpoint.
