Hi,
What's interesting (for me) is that I have an iSight too (MacBookPro
mid-2007), but the camera is (05ac:8502). And it works with uvc, while
yours not. And grep 850 ~/linux-uvc prints only *yours* (8501):
Could you please post the output of lsusb -d 05ac:8502 -v (using usbutils 0.72
or newer, go for the latest version if possible) ?
snoopy:~/linux-uvc$ grep 850 *
uvc_driver.c: .idProduct = 0x8501,
Binary file uvcvideo.ko matches
uvcvideo.mod.c:MODULE_ALIAS("usb:v05ACp8501d*dc*dsc*dp*ic*isc*ip*");
Binary file uvcvideo.mod.o matches
snoopy:~/linux-uvc$
