16.04 No Driver for Integrated Webcam
I upgraded to Ubuntu 16.04 and my integrated webcam is no longer working. From what I can tell, it's completely missing a driver.
Below are the results of lsusb -t./: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/14p, 480M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/6p, 480M |__ Port 3: Dev 3, If 0, Class=Wireless, Driver=btusb, 12M |__ Port 3: Dev 3, If 1, Class=Wireless, Driver=btusb, 12M |__ Port 4: Dev 5, If 0, Class=Video, Driver=, 480M |__ Port 4: Dev 5, If 1, Class=Video, Driver=, 480M
As you can see, the driver is clearly missing. If I press fn+f6 (my webcam hotkey) to toggle off webcam and run lsusb -t again then associated lines completely disappear (as they should).
Any thoughts or ideas?

If your webcam required the use of a third party driver, 16.04 requires the use of all drivers to be signed with a key. You can get around this by turning off secure boot in your BIOS.
To check for a driver, go to terminal and type "dkms status". List any output here. If it says dkms not found, then there's no driver installed this way.
You can also open "Software & Updates" from the dash, and check the additional drivers tab.
