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) ?
This seems to be interesting. I have attached lsusb and dmesg of the
device one time with firmware loaded and another with no firmware
loaded. Both are attached.
I compiled the latest cvs lsusb as of today.
Earlier the device did change its usb id with loading the firmware ...
