[Bug 544469] Re: iSight webcam on Macbook Pro does not work

I experience exactly the same problem, what is more, it seems that ift-
load has the 05ac:8300 ID hard-coded into it, so even changing the udev-
rule doesn't change anything (my isight webcam registers as 05ac:8507)

reloading uvcvideo gives me the already known output:

[  247.745593] uvcvideo: Found UVC 1.00 device Built-in iSight (05ac:8507)
[  247.745605] uvcvideo: No valid video chain found.
[  247.745643] usbcore: registered new interface driver uvcvideo

and trying to manually load the firmware

sudo /usr/lib/udev/ift-load --firmware /lib/firmware/isight.fw

gives the following output:

ift-load: USB device 0x05AC:0x8300 not found
ift-load: No iSight found

it seems the loader always looks for the device with the ID
0x05AC:0x8300, whereas the actual ID seems to vary. does this make any
sense?

this would also explain why the webcam works after rebooting from OSX -
the firmware is already loaded so ift-load isn't needed.

i hope this helps, thanks.
