The webcam on my System76 laptop (serp7) worked fine with Ubuntu 12.04 but after upgrading to 13.10 and later to 14.04, the webcam has stopped working. I don't even have a /dev/video0 directory. If I use a USB webcam, it works fine. I've attached my dmesg, lsusb, and lsmod outputs. I know it worked before and it's not because I didn't press Fn+F10. Nothing in the output of dmesg, lsusb, or lsmod changes after pressing Fn+F10. Was support for this webcam depricated in the kernel update? How would I find out what chipset my camera is if it's not showing up in any of the outputs?
