Hi,
I'm writing here since it seems that now, iSight code seems to be part
of UVC. And I'm having a problem with it (/dev/video0 not created).
So I built the uvcvideo driver (trunk r217) and built iSight Firmware
Tools 1.2 (and restarted HAL). When I load the driver, dmesg only tells
me:
usbcore: registered new interface driver uvcvideo
Nothing else.
if I modprobe uvcvideo race=255, I get:

usbcore: registered new interface driver uvcvideo
The problem is that no device /dev/video0 is created, so gstreamer
fails with a message like
Error running pipeline 'Video for Linux 2 (v4l2)': Cannot identify device
'/dev/video0'. [v4l2_calls.c(429): gst_v4l2_open (): /pipeline0/v4l2src3:
system error: No such file or directory]
I don't think that's a problem regarding the firmware loading since I
used an old binary called 'extract' that worked back in time. It tells
me that the iSight firmware is loaded:
Apple iSight with firmware already loaded found
Apple iSight with firmware already loaded found

Do you have any ideas about this problem ?
Some months ago, my webcam worked with a driver derived from uvcvideo.
but that was with the previous kernel. Now it no longer compiles.
Thanks
