Are you sure? with http://cateee.net/lkddb/web-lkddb/USB_BDC_UDC.html, this device looks like a USB 3 peripheral controller in a Broadcom SoC. The FaceTime is known as USB device, if yours is in the "lsusb" output then it is probably not related to this device.

Hey, yes, I'm fairly certain. The camera on the latest Macbook Pro (MBP11,3) uses the PCIe bus to transmit raw 720p video, it seems. It appears that there is no linux-compatible driver for it at the moment and that Broadcom has not released any information on this device to help with that. This issue has been filed both on the Arch Linux wiki and Kernel.org bug tracker:
https://wiki.archlinux.org/index.php/MacBookPro11,x#Web_cam
https://bugzilla.kernel.org/show_bug.cgi?id=71131

There is an effort in progress to reverse-engineer construct a linux driver for this on GitHub:

Thank you for the information. I have accepted the entry for the moment; may do some further research on it as it still bothers me that the bdc module also claims this ID.
